Abstract

A reentrant resonant cavity applicator is analyzed as a generalized eigenvalue problem by using the finite element method (FEM) with edge elements. The subspace iteration method is used to solve for selected eigenvalues. The resonant frequencies obtained are in good agreement with both the measured values and with the ones obtained using the finite-difference time-domain (FD-TD) method. Computation time and the amount of memory required are also discussed
