TLDR
The effect of using thin-wire approximation in the integral equation solution of radiating antennas is discussed in this paper, where it is shown that these effects can cause large errors in the solution at high frequencies and may cause appreciable error in the response of the antenna if it is calculated by Fourier inversion.Abstract:
The effect of using the thin-wire approximation in the integral equation solution of radiating antennas is discussed in this communication. In addition, the effect of having a source region which varies with the number of matching points used for solving the integral equation is considered. It is found that these effects can cause large errors in the solution at high frequencies and may cause appreciable error in the time domain response of the antenna if it is calculated by Fourier inversion.read more

Analysis of antennas and scatterers with nonlinear loads
TL;DR: In this article, two methods for analyzing antennas or scatterers having nonlinear resistive loads are discussed, one is a direct time-domain integral equation approach, whereas the second involves the use of frequency domain data to compute the time-dependent currents and voltages across the nonlinear load.

The exact kernel for cylindrical antenna
TL;DR: In this paper, the exact kernel for the cylindrical antenna was derived for a single-input, single-out (SISO) case, where the radius of wire is much less than its length and the wavelength.
