Time Domain Wave Propagation in Multilayered Integrated Circuits
Abstract
Under the sponsorship of the ONR Contract N00014-86-K-0533 we have published 15 referenced journal and conference papers on time domain electromagnetic waves in multilayer media. A rigorous dyadic Green's function formulation in the spectral domain is used to study to dispersion characteristics of signal strip lines in the presence of metallic crossing strips. A set of coupled vector integral equations for the current distribution on the conductors is derived. Galerkin's method is then applied to derive the matrix eigenvalue equation for the propagation constant. The dispersion properties of the signal lines are studied for both cases of finite and infinite length crossing strips. The effects of the structure dimensions on the passband and stopband characteristics are investigated. For crossing strips of finite length, the stopband is mainly and affected by the period, the crossing strip length, and the separation between the signal and the crossing strips. For crossing strips of infinite length carrying traveling waves, attenuation along the signal line exists over the whole frequency range of operation. In order to provide shorter interconnects between chips, modern multilayer integrated circuit packages for high-performance mainframe computers employ not only conventional striplines but vertical transmission lines or so-called vias as well. Because vias may be of comparable length with the striplines, the study of transient electromagnetic wave propagation on the former is equally indispensable to the understanding of how fast the multilayer integrated circuits can operate.
