An integro-differential equation technique for the time-domain analysis of thin-wire structures. II. Numerical results

Presented here are the numerical results from a computer solution of the time-dependent thin-wire electric-field integral equation described in Part I of this paper. Both radiation and scattering problems are considered. The present results are validated by their Fourier transform of the frequency domain, where they are compared with independently computed data. A space-time sampling criterion is derived for predicting the highest frequency to which the time-domain calculations are accurate and found to be in accord with the numerical results. The time domain results are also shown to provide informative insights into the radiation characteristics of specific structures. Recommendations for further work are also presented.
