Simple Analytic Formulas for the Nonlocal Field Generated by Circuit Elements in Multilayer Structures

Robert W. Jackson Senior Member, IEEE

Page 1967.

Abstract:

Simple analytic expressions are derived for the distant field generated by surface currents or via currents in a three-dielectric-layer parallel-plate structure. These expressions are useful for coupling calculations applied to microwave multichip assemblies. Their simplicity results from making low-frequency approximations; however, their accuracy is sufficient for coupling calculations up to millimeter-wave frequencies in typical structures. They are validated by comparison to numerically determined results. Examination of these equations reveals some general characteristics of coupling in multilayer configurations.
