An approach to singularity cancelation by a variable transformation of Green’s function in 2-D case, having log( $R$ ) singularity, is outlined. It is intended for the method of moments analysis of 2-D structures of both curvilinear and flat cross

Excess attenuation of electric field of an electromagnetic wave propagating through deciduous forest is approximated with two novel analytical formulas. The coefficients of those formulas were obtained through a computationally intensive optimization

We present an overview of the recent advances in numerical analysis of 2-D structures using singularity-cancellation transformations in conjunction with entire-domain higher-order analysis. It is demonstrated that the transformation allows high-preci

We summarize results for using Gegenbauer polynomials as basis functions in the case of the entire-domain 2-D analysis of strips with curvilinear cross section illuminated by a linearly-polarized plane wave. The involved integrals are calculated with

We present a formula that can approximate the excess attenuation of electric field of electromagnetic wave propagating in the presence of human crowds. The formula is tested on results obtained from full-wave simulations of 2D and 3D stochastic model
