Pulsed EM-field coupling between bounded and narrow conductive screens

Abstract

In order to evaluate electromagnetic (EM) phenomena such as cross talk or substrate noise coupling in thin-film multilayered structures, the pulsed EM field interaction between conductive strips has to be properly incorporated in a computational model. This is exactly the main purpose of this chapter, where it is demonstrated how mutual-coupling effects can be included in the Cagniard-DeHoop method of moments (CdH-MoM). Again, the main mathematical tool for the analysis is the EM reciprocity theorem of the time-convolution type. The reciprocity-based formulation yields a reciprocity relation that is upon discretizing the (space-time) solution domain cast into its matrix form, elements of which represent local and remote interactions involved. A few illustrative examples, including the EM coupling between two plane screens on the dielectric half-space and on the grounded dielectric slab, are discussed and analyzed in detail. More complex problems can be analyzed along the same lines.
