TL;DR: In this article, the authors used Numerical Maxwell Model in 3D Simulations (NMM3D) to study the backscattering coefficients, coherent reflectivities, and emissivities of soil surfaces using Gaussian random rough surfaces with exponential correlation functions.

TL;DR: A time-series algorithm to retrieve bare surface soil moisture and rms height using two copolarized L-band backscattering coefficients (σ0) is proposed and it is shown that retrieval performance is not sensitive to errors in knowledge of the surface roughness correlation length for most of the bare surface conditions examined.

TL;DR: The electromagnetic full-wave simulations for scattering of waves by soil surfaces, bistatic scattering, backscattering, and emissivity which are signatures measured in microwave remote sensing are reviewed.

TL;DR: A hybrid UV/PBTG/SMCG method is developed to accelerate the solution of NMM3D for 3-D electromagnetic wave scattering by random rough soil surfaces and numerical results show that for a single realization VH = HV within 0.5 dB in the backscattering direction showing that reciprocity is obeyed.

TL;DR: In this article, the authors developed the method of broadband Green's function with low-wavenumber extraction (BBGFL) for arbitrary shaped waveguide for broadband simulations of vias in printed circuit boards (PCB).
