An improved algorithm for indirect time domain analysis of thin wire structures

The algorithm for an indirect time domain (TD) analysis using arbitrary frequency domain method is presented. In previous work, an optimized version of the indirect time-domain method based on adaptive sampling iterative algorithm used in combination with Inverse Fast Fourier Transform (FFT) was presented. In this paper, the algorithm is further improved by circumventing the use of FFT altogether, and using the simple formula based on the analytical inverse Fourier transform. The proposed approach is faster and more convenient for use with the underlying iterative optimization method, as only a part of the frequency domain (FD) signal has to be transformed to the time domain during each iteration procedure.
