Transmission Studies of Left-handed Materials
, 2001 Left-handed materials are studied numerically using an improved version of the transfer-matrix method. The transmission, reflection, the phase of the reflection and the absorption are calculated and compared with experiments for both single split-ring ...

Optimizing the Drude-Lorentz model for material permittivity: Examples for semiconductors [PDF]
, 2017 Approximating the frequency dispersion of the permittivity of materials with simple analytical functions is of fundamental importance for understanding and modeling their optical properties. Quite generally, the permittivity can be treated in the complex

Physics Assisted Deep Learning for Indoor Imaging using Phaseless Wi-Fi Measurements [PDF]
, 2021 A physics assisted deep learning framework to perform accurate indoor imaging using phaseless Wi-Fi measurements is proposed. It is able to image objects that are large (compared to wavelength) and have high permittivity values, that existing radio frequency (RF) inverse scattering techniques find very challenging, making it suitable for indoor RF ...
