The surface resistance of

superconducting films is

inversely proportional to the

critical current density

Applied Superconductivity 13 (2003) 3578

In order to increase Jc of YBCO

films Reduction of grain boundary

density is important

Our groupWe could control the density of 45-degree tilt grain by

template deposition method of laser deposition method

and we examined the relationship between its density

and surface resistance

We found that grain boundary increases the Rs of YBCO thin films Therefore

it is important to make thin films with perfect c plane oriented film

21 Electrical small antennas

Half wave length antenna(Yagi antenna)

Normally we cannot use a electrical

small antenna because efficiency is

small However the efficiency of

superconducting electrical small

antenna is large even in very small size

Therefore the first focused microwave

device was an electrical small antenna

when HTS was discovered

Helical antenna

Unfortunately the HTS antennas could not

be used for practical application because of

Cooling problem

The gain of the HTS helical antenna is 5 dB or more

as compared with that of copper antenna at 80K

A helical antenna is one of the electrical small antenna

And they can reduce a size of 140 of the wave length

Reported in ISSrsquo92

NTT group


11

Patch array antenna

The helical antenna cannot be cooled by a small

refrigerator and that is a serious problem for

practical use However patch antennas can be

cooled by a small refrigerator and easy to cool

Mini cryocooler for a patch antenna

The superiority of the superconducting

antenna could be demonstrated but it could

not be put into practical use Superconducting

antennas must be cooled to a low temperature

and that is large disadvantage

use electromagnetic waves with a low absorption in the air

Relationship between frequency and absorptivity of air


19

MKIDs

MKID is an excellent element for detecting Terahertz waves

Principle of MKIDs When Terahertz waves are irradiated to

superconducting LC resonators resonance frequency is shifted

to lower side because cooper pairs are broken That is we can

detect Terahertz wave by using ~GHz resonator

Merits of MKIDs

(1) Easy to array (can be more than 10000 pixels)

(2) Only Two lines of input output (coplanar shape)

(3) High sensitivity

TES X-ray microcalorimeters for X-ray astronomy and material analysis

TES X-ray microcalorimeter arrays provide not only high-energy resolution (FWHM lt 10eV) in X-ray

spectroscopy but also imaging and high-counting-rate capabilities They are very promising spectrometer for X-

ray astronomy and material analysis In this paper we report our recent progress For material analysis we have

fabricated 8 x 8 format array with a fast signal response (40 mu s) and proved the energy resolution of 58 eV

FWHM at 59 keV We developed common biasing scheme to reduce number of wirings from room temperature

to the cryogenic stage From measurements using the newly-designed common-bias SQUID array amplifier chips

and from numerical simulations we demonstrated that signal cross talks due to the common bias is enough small

For space applications we are developing frequency-division signal multiplexing system We have fabricated a

baseband feedback system and demonstrated that the noise added by the feedback system is about 4 eV FWHM

equivalent for 16 ch multiplexing system The digital to analog converter (DAC) dominates the noise and needs

be reduced by a factor of four for future astronomy missions (C) 2016 Elsevier BV All rights reserved

Narrow band pass filter required

Weather radar is important to detect the density and moving

speed of rain clouds however used wide frequency band is

trouble to other system It is necessary to narrow the band width

The MIAC policy

Some 5GHz-band is released for wireless communication so we need

narrower the bandwidth of the weather radar

Narrow-band filter

In the case of a narrow band filter the

insertion loss increases when we use large

surface resistance materials

For superconducting bandpass

filters insertion loss is quite small

and skirt property is quite sharp

Therefore it is suitable for weather

5 Summary

Looking back on the 30 years of superconducting microwave

devices we can see that the research has greatly evolved

from basic research into practical application research

For example the superconducting bandpass filters are used

not only in the field of mobile communication but also for

radio astronomy field and weather radar Microwave and

Terahertz detector of high sensitivity also evolve from the

security field to receiving weak radio waves from space As a

new development in the future I think that the development of

composite device is important for example with

semiconductors and magnetic materials I am expecting

future development
