Complex source point (CSP) beams (or CSPBs) are known to be exact solutions of
Maxwell's equations. Hence they can be used as basis functions to represent the …

A solution for the calculation of three-dimensional (3D) eigenrays based on Simplex
optimization, implemented in a 3D Gaussian beam model, is investigated in this paper. The …

Outdoor sound propagation benefits from algorithms that can handle, in a computationally
efficient manner, inhomogeneous media, complex boundary surfaces, and large spatial …

We present two novel beam-summation schemes for radiation from time-harmonic or time-
dependent volume source distributions, where the field is expanded using a discrete phase …

A method for the fast computation of radiation by Gaussian windows, with controllable error,
is presented. The computation aims to complement beam summation frameworks as an …

The diffracted field due to a general 3-D Gaussian beam (GB) impinging close to an edge of
a half-plane is expressed as a sum of diffracted GB's emerging from a discrete set of points …

We present an ultra-wide-band beam-summation (UWB-BS) algorithm for calculating the
radar cross-section (RCS) of large smooth targets whose asymptotic numerical complexity is …

A Gaussian beam summation (GBS) representation for half plane diffraction of an incident
two dimensional Gaussian beam (GB) that hits arbitrarily close to the edge is presented. The …

We present a beam summation (BS) representation for the field scattered by an impedance
wedge illuminated by a general 3D electromagnetic Gaussian beam (EM-GB). The …

We introduce a Gaussian beams summation (GBS) scheme for radiation from a source
distribution along a line in a 3-D configuration. The expansion is based on a discrete phase …
