Time Domain Electromagnetic Waves in Multilayered Media

摘要

The purpose of this research project is to study the time domain response ofelectromagnetic wave radiation, transmission and coupling in multilayered media. The following problems are pursued: (1) extensions and modifications to the double deformation technique; (2) propagation in nonconventional transmission structures; (3) signal distortion at discontinuities; (4) the effects of anisotropic material and nonlinear loads; (5) limitation of quasi-TEM approximation. We shall emphasize and seek to refine a powerful transform-domain formulation, the double deformation technique in order to have a unified way of interpreting the results. Yet other techniques such as the space-time domain integral equation method, the transmission line matrix method, the method of characteristics, and the method of moments are also to be applied to different problems as demanded by efficiency or ease of formulation. The research results can be applied to computer-aided design of high-speed microelectronic integrated circuits, as well as to time-domain geophysics sub-surface probing, and active remote sensing with transient radar pulses.
