Some composite boundary value problems in electromagnetics and their applications
… some composite boundary value problems of stratified media with various types of discontinuities are discussed. These problems fall into three categories: (i) a disk on top of a stratified medium; (ii) a general multiregion vertically stratified medium; and (iii) a slantingly stratified …

Numerical Methods for the Electromagnetic Modeling of Microstrip Antennas and Feed Systems
… and simplify the analysis of multilayered or stratified media. This thesis derives the dyadic Green functions for the electromagnetic fields in a multilayered medium and shows their relationship to the more familiar Green functions for ordinary transmission lines. This approach simplifies the …

Scattering Techniques for the Geophysical Inverse Problem
… problem for the propagation of elastic waves in stratified media. The one-dimensional inverse problem for the propagation of shear waves is studied in the context of spectral theory. We generalize certain inverse scattering methods in quantum mechanics to determine the properties of the …

Modern electromagnetic scattering
… electromagnetic wave propagation through planar stratified media. This algorithm is implemented in a modern programming language and is suitable for the study of such applications as Anderson localization and perfect lensing. Our algorithm remains numerically stable even in the presence of large …

Wave motion in finite and infinite media using the Thin-Layer Method
… problems involving partially heterogeneous media. While the method has been used widely for horizontally stratified media, e.g. dynamic response of foundations over layered soils, there remain many unexplored aspects. These include a thorough evaluation of the TLM's accuracy and range of …

A study on computational electromagnetics problems with applications to casimir force calculations
… of the dyadic Green's function for layered media (DGLM) and the calculation of the Casimir force using computational electromagnetics (CEM). The calculation of the DGLM is desirable for many problems that involve stratified media, like the cases of the subsurface of the earth and seabed, or …
