Cutoff space of cloverleaf resonators with electric and magnetic walls

A planar resonator that has the symmetry of a junction circulator is the cloverleaf resonator. The isotropic cutoff space of this class of resonator is described using the finite-element approach. Circuits with threefold and fourfold symmetries and with a magnetic or an electric sidewall are separately dealt with. Standing-wave solutions are included for completeness. The gyromagnetic problem is separately investigated.<
