During recent years, we have been developing an efficient time domain technique based on numerical inversion of Laplace transform (NILT), for modelling pulse reflection from a lossy or dispersive dielectric half space and pulse propagation in a dispersive medium. In this paper, this technique is extended and applied to transient analysis of electromagnetic pulses reflected from a layered medium, with...
In this paper, an efficient technique is developed to solve the inverse transform of exact closed form representations of frequency domain surface impedances, without pursuing tedious and complicated mathematical manipulations. This technique is based on the numerical inversion of the Laplace transform and has the advantages of simple programming, computational efficiency and easy error control. The...
In this paper, an efficient time domain technique is developed to solve the impulse response of a Debye half space without performing tedious and complicated mathematical manipulations. Both horizontally and vertically polarized plane waves that are obliquely incident onto the interface between free space and a Debye medium are discussed. This technique is based on numerical inversion of Laplace transform,...
A time domain technique on the basis of numerical inversion of Laplace transform is extended and applied to transient analysis of pulses propagating in plasma. Its correctness and effectiveness are validated by comparing our results with those published in the literature. This technique leads to good accuracy in both late and early time, and has a simple algorithm, short calculation time, small required...
An efficient time domain technique on the basis of numerical inversion of Laplace transform and Prony's method is extended to the transient analysis of ultra wideband pulses transmitting through a lossy dielectric slab. The results obtained using this technique agree with those obtained using the FDTD technique, and are consistent with those published in the literature. Furthermore, the corresponding...
