INTERPRETATION AND APPLICATION OF TRANSIENT AND IMPULSE RESPONSE APPROXIMATIONS IN ELECTROMAGNETIC SCATTERING PROBLEMS

Abstract

A linear system analysis is applied to electromagnetic scattering problems. The relationship between the incident and scattered fields is reduced to a one-dimensional linear system by suitable restrictions, and modeled as a linear two-port with time-invariant parameters. The two-port characterized by a real, time-dependent impulse response function and a transform-related complex, frequency-dependent phasor response. Two fundamental approaches for obtaining approximate solutions to electromagnetic scattering problems are seen. Estimates of either the frequency-dependent phasor response or the time- dependent impulse response can be attempted. The material in this study is concerned with the latter approach.
