UWBRAD meeting May 6, 2014 Leung Tsang, Shurun Tan, Tianlin Wang Coherent Wave Effects in Layering Slide 2 Physics Slide 3 Model of Layering Effects Density profile: (Drinkwater 2004) Modified by damping Gaussian Noise (Macelloni and Brogioni) Standard deviation Damping factor Layer thickness: Average of layer thickness Standard deviation of layer thickness Total layer thickness Slide 4 Reflection and Emission Effective permittivity: Absorption coefficient: No scattering effects included in current model. Focus on coherent wave interference. Maxwell-Garnett mixing formula Ice permittivity empirical model of Matzler and Wegmuller, 2006 Slide 5 Temperature Profile Temperature profile (Jezek et al. 2013) Slide 6 Incoherent model is not sensitive to layer thickness variation. Tb of coherent model shows less resonance as standard deviation of thickness increase. Slide 7 Incoherent model is not sensitive to layer thickness variation. Tb of coherent model shows less resonance as standard deviation of thickness increase. Slide 8 Slide 9
