Research efforts in support of resonance extraction studies. Volume 1: Improvement and validation of TWFD (Thin-Wire Frequency-Domain): A thin-wire frequency-domain scattering code
Abstract
The development of a thin-wire frequency-domain (TWFD) method of moments code was discussed in a previous report 1. Since that time this code has undergone further development and numerical testing. The purpose of the code is to provide a theoretical and numerical basis to aid in understanding the resonance region electromagnetic scattering from thin-wire stick models. This frequency domain code augments a time-domain code (TWTD) which calculates the scattered transient response for an impulsive incident field. The outputs from both of these codes have provided numerical predictions which have been indispensible in assessing our ability to extract resonance information from actual scattering range data.
