An important extension of the two-level discrete complex image method is proposed to
eliminate any concerns on and shortcomings of the approximations of the spatial-domain …

The classic weighted averages (WA) algorithm for the evaluation of Sommerfeld-like
integrals is reviewed and reappraised. As a result, a new version of the WA algorithm, called …

Sommerfeld-integrals (SIs) are ubiquitous in the analysis of problems involving antennas
and scatterers embedded in planar multilayered media. It is well known that the oscillating …

A direct integration algorithm, based on double exponential-type quadrature rules, is
presented for the efficient computation of the Sommerfeld integral tails, arising in the …

The rational function fitting method has been found useful in the derivation of closed-form
expressions of spatial-domain Green's functions for multilayered media. However, former …

The analysis of propagation of bound and leaky modes in single and multiple coupled
microstrip lines in planarly layered media by means of Galerkin's method applied to an …

A fast and accurate approach, based on the fast all-modes method (FAM) and the numerical
modified steepest descent path method (NMSP), was previously used to calculate the spatial …

This paper presents an algorithm for the acceleration of the series involved in the
computation of 2-D homogeneous Green's functions with 1-D and 2-D periodicities. The …

We introduce the Vector Fitting algorithm for the creation of reduced order models from the
sampled response of a linear time-invariant system. This datadriven approach to reduction is …

Far-field closed-form expressions are derived for spatial domain multilayered Green's
functions (GF). For the derivation of these far-field expressions, the spectral domain …
