A comparison of perturbation formulas for a square electromagnetic resonator

Abstract

Several perturbation formulas are available for the resonant frequency of an electromagnetic cavity subjected to shape and material perturbations. Each is based on a mathematical identity from vector calculus, a choice of trial fields, and the manner in which the boundary conditions are met. The limits of usefulness of a given perturbation formula depend on… (More)
