Finite-element analysis of axisymmetric cavity resonator using a hybrid edge element technique

A modified finite-element technique for the analysis of axisymmetric cavities is presented. In this analysis an edge element approach is used in conjunction with a nodal approach to represent all electric field components in the cavity. A bilinear functional is formulated from which resonant frequencies and/or field distributions are obtained. Several geometries are investigated and corresponding results are presented as verification of the method.<
