LOSSY SPHERICAL CAVITY RESONATORS FOR STRESS-TESTING ARBITRARY 3D EIGENMODE SOLVERS
2015
Electromagnetic Waves
A lossy metal-wall cavity resonator that extends well beyond perturbation theory limits is studied. An exact analytical solution is employed for the spherical cavity resonator, having walls transformed from being a perfect electrical conductor (PEC) to free space. This model then acts as an ideal benchmark reference standard. A plane-wave approximation is then derived. Independent full-wave numerical modeling of the spherical cavity resonator is undertaken using eigenmode solvers within two
