1. UWBRAD meeting May 6, 2014 Leung Tsang, Shurun Tan, Tianlin Wang Coherent Wave Effects in Layering

2. Physics

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

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

5. Temperature Profile Temperature profile (Jezek et al. 2013)

6. Incoherent model is not sensitive to layer thickness variation. Tb of coherent model shows less resonance as standard deviation of thickness increase.
