ABSTRACT
The emergence of complex high-speed digital interconnecting structures has initiated the research into efficient yet reliable modeling techniques capable of describing pulsed transmission characteristics of planar structures. Having the indispensable impact of relaxation phenomena on the signal transfer on mind, the main objective of this chapter is to provide an efficient modeling technique that allows us to analyze the space-time field distribution within a rectangular planar circuit with relaxation behavior in its dielectric filling. This chapter discusses the relation between the ray-like solution and the standard Eigen function expansion for a rectangular circuit with the instantaneously reacting filling. It provides the closed-form solution for a rectangular planar circuit whose dielectric losses are accounted for by its electric conductivity. An efficient modeling technique for analyzing the pulsed Electromagnetic-field transmission over a rectangular planar circuit has been described. This technique is based on the method of images and allows for the inclusion of rather general relaxation mechanisms.
