Abstract

The drawbacks of conventional power-bus impedance, defined as an average Green´s function integration over port areas, are discussed. A new definition is proposed in terms of cylindrical waves. The equivalence of the new definition and the conventional one is proved in the case of electrically small ports. Addition theorems of cylindrical waves are used to derive an analytical expression of power-bus impedance between ports in a circular plate pair with perfectly electric/magnetic conductor (PEC/PMC) boundaries as well as non-reflective perfectly matched layer (PML) for infinite plate pair. Numerical method has been used to validate the analytical expression derived.
