Keynote Talks

Metasurfing Wave Antennas

Stefano MaciDepartment of Information

EngineeringUniversity of Siena, Italy

Metasurfaces constitute a class of thin metamaterials, which are usedfrom microwave to optical regime to create new antennas and microwavedevices. In this talk, we propose the use of variable-impedance metasur-faces for transforming surface or guided waves into a different configura-tion of wavefield with desirable properties. We will shortly refer to thismetasurface-driven wavefield transformation as "Metasurfing". Meta-surfing can be obtained by an appropriate synthesis of inhomogeneoussurface impedance that allows a local modification of the dispersion equa-tion and, at constant operating frequency, of the local wavevector. Thegeneral effects of metasurface modulation are similar to those obtainedin solid (volumetric) inhomogeneous metamaterial as predicted by theTransformation Optics, namely re-addressing the propagation path ofan incident wave; however, significant technological simplicity is gained.Several examples of metasurfing wave antennas are shown as a proof ofconcept; among them Luneburg lenses, spiral lenses and isoflux circularlypolarized antennas for low satellite orbits.

Graphen-Based Electronics for RF Applications

Tomás PalaciosDepartment of Electrical Engineering

and Computer ScienceMassachusetts Institute of

Technology, USA

Electrical engineering is at a crossroads. For the last fifty years, semicon-ductors have been driving the development of information technology,which has completely transformed our society. Conventional electronics,however, is reaching scaling and performance limits which jeopardizes fu-ture developments. New materials with unique properties are necessaryand graphene, a one atom thick layer of sp2 bonded carbon, is at thetop of potential candidates. Graphene not only has outstanding transportproperties, but it also shows many unique properties not found in anyother high performance electronic material. It is flexible, transparent,ultimately scalable, easily transferable to any surface, and its ambipo-lar conduction offers new possibilities for advanced electronics. In thistalk, we describe how the use of these properties allows the developmentof new devices, which can overcome some of the main limitations oftraditional electronics in terms of sensitivity, maximum frequency, andlinearity. Several novel devices will be discussed for RF communicationsand remote sensing, including graphene frequency multipliers, grapheneRF mixers and graphene chemical sensors.

Keynote Talk

The Challenge of Cognitive Radio

Frederic VillainPrincipal IC Architect

NXP Semiconductors, France

The presentation on “THE CHALLENGES OF COGNITIVE RADIO” willelaborate on the opportunities/challenges imposed by Cognitive Radios.Also, methods to meet the RF challenges will be discussed.

The opportunities include:

• More efficient usage of the newly available frequency spectrum(White Spaces) in the unused TV band.

• The evolution of a new class of devices called “White Space Devices”,which can complement the existing Wi-Fi/Internet providers by ex-tending their range of operation or/and can also be used to providelow cost, broadband services in rural areas.

The challenges include:

• Developing a spectrum sensing algorithm which enables the Cogni-tive Radio to co-exist with the licensed users by also ensuring thecomplete protection of the incumbent users.

• Integrating the different features of Cognitive Radio such as spec-trum sensing, spectrum management, spectrum mobility and spec-trum sharing into a single device, in both IC and system level.

• Justifying the RF constraints imposed on the devices operating inthe TV band.


GeM

iC2012

PlenarySessionsThis talk will review the expected performances and design considera-

tion of future cognitive radio particularly at IC level but also at systemlevel. In addition, possible ways to meet the RF challenges will also bediscussed.

The past history of unlicensed systems such as Wi-Fi or Bluetooth sys-tems and their massive adoption indicates that prescribed standards areneither intended nor sufficient for non interference in co-located radios.Although the design/implementation of a Cognitive Radio is challenging,it has tremendous potential to bring about a new class of devices in thefuture wireless communication systems. Cognitive Radios (CR) take intoaccount the real time conditions of the environment. This feature of CRcoupled with Dynamic Spectrum Access (DSA) could provide reliableand flexible spectrum usage and thus looks very promising to pursuefurther research.

Commercial integral equation solvers for so-called planar 3D struc-tures typically have very comfortable features for structure editing,parametrization and meshing capabilities, which are very useful for afast design and optimization of antennas and subsequent signal process-ing circuitry. However, in many cases, commercial solvers may providedoubtful and unreliable results, thus a further examination with addi-tional full wave analysis tools is necessary. For this goal an in-house inte-gral equations solver framework is used allowing a complete insight andcontrol of the overall solution process.

WS 1: SatCom Ka-Band

08:30 - 12:00 / Fraunhofer Testbed: Am Vogelherd 61

M. Mehnert (Fraunhofer IIS), K. Blau (TU Ilmenau),M. Hein (TU Ilmenau)

Since designated technologies and applications have been establishedworldwide successfully and abundantly, satellite communications have re-cently attracted renewed interest and R&D efforts. This encouragingdevelopment reflects the ongoing exploration of Ka-band frequencies, of-fering the potential for multi-spot beam antennas and compact groundterminals for nomadic or mobile operation. Another driving force is thegrowing demand for on-board signal processing, to accommodate morefeatures and higher data rates with optimised link budgets.This workshop addresses recent industrial and academic developments inboth the satellite segment and the ground segment for satellite commu-nications at Ka-band frequencies. Most achievements, like the BMWi-funded projects SANTANA, KERAMIS-GEO, or MoSaKa, result fromsustainable public funding, recently focusing on the German geostation-ary Heinrich Hertz satellite mission (H2SAT).This workshop will be hosted by the Fraunhofer project group “DrahtloseVerteilsysteme – DVT” in the premises of their research facility for satel-lite communications “Am Vogelherd” in the city of Ilmenau. Participantswill also have the opportunity to visit this unique research and test site.

WS 2a/b: Microwave Measurements

10:20 - 12:00 and 14:20 - 15:40 / HU 201

J. Sachs (Ilmsens)

A detailed description of the high-frequency reflectometer technologydeployed in Anritsu’s Vector Network Analyzer (VNA) family will begiven. It will be shown that scaling of this technology for use in themillimeter-wave range results in miniature frequency-extension modulesthat provide unique capabilities such as direct connection to wafer probes,dense multi-port measurements, test-port power leveling, enhanced rawdirectivity, and reduced measurement complexity when compared withexisting solutions. These capabilities, combined with the frequency-scalable nature of the extension modules provide users with unique andcompelling solutions for their current and future high-frequency measure-ment needs. Applications of this technology beyond traditional test andmeasurement will be described.The use of pseudo-noise (PN) signals instead of sine waves or sub-nanosecond pulses permits the construction of robust and lightweightRF-devices of 200% fractional bandwidth, large measurement speed andvery high temporal stability. A theoretically arbitrary number of basicPN-units can be cascaded by a Master-Slave principle to large MiMo-systems and the user can freely selects between time or frequency do-main operation. The presentation will give an overview of the functionprinciple, various device configurations and application examples. A livedemonstration will illustrate the device performance. The shown exam-ples will refer to recent research projects in non-destructive testing andhigh-resolution short-range sensing as well as to experiments of wavepropagation phenomena for educational purposes.This workshop gives an overview of millimeter wave measurements upto 500GHz with the R&S vector network analyzer ZVA. Above 70GHzmillimeter wave converters expand the analyzer´s frequency range. Theoperation principle of a frequency converter will be explained, followedby an explanation of possible calibration techniques. A typical measure-ment on a waveguide WR10 bandpass filter will be demonstrated. Finallythe requirements and special needs for On-Wafer measurements will beexplained.

WS 7: Cognitive Radio

14:20 - 18:00 / HU-Hs

R. Thomä (TU Ilmenau)

The cognitive radio paradigm is expected to provide another importantstep for a more efficient use of the sparse radio resources. Moreover,cognitive self-organized radio access schemes may have the potentialto reduce installation and operation expenses and allow radio networksadapting to different and varying situations, scenarios, and user needs.This requires gaining situation awareness and learning about availableresources, making reasonable decisions and adjusting the access param-eters according to global rules. So cognitive radio has many facets alsoincluding the functionality of RF interfaces and radio aspects. The in-tention of this workshop is to provide a discussion platform on cognitiveradio. For that purpose we have invited several German research groupsand projects working on this topic.

Capital city of Erfurt

Petersberg – Guided tour including the secret listening passages.

The Petersberg is an elevation of 231 meters in the city centre of Erfurt.On this area extends the Citadel Petersberg. Inside is the “Peterskirche”,once the largest Romanesque abbey church of Thuringia.


Under the Archbishop Johann Philipp von Schönborn in the mid-17thCentury, the site of Petersberg became a fortress - the Citadel Peters-berg. Then it was up to the 60s with short breaks one of the key militarysites in the region. With the beginning of the 19th Century, Petersbergwas temporarily occupied by Prussian and French forces.We will guide you through the Petersberg and the secret listening pas-sages of the fortress.Since the tour needs at least 15 participants we ask you to indicate yourbinding participation when you register for the conference.
