Description
A field-driven method is presented for synthesising multipolar transverse-electric cavities. Cylindrical standing-wave TE solutions are superimposed analytically, and the cavity surface is reconstructed by enforcing perfect-electric-conductor boundary conditions. The method produces closed hybrid cavity geometries whose modal content is validated against CST eigenmode simulations. Two examples are shown: TE$_{\{0,2\}1}$ and TE$_{\{2,4\}1}$ hybrid cavities. In both cases, the intended azimuthal field structure is preserved with sub-percent-level agreement between the analytic model and CST. The method provides a route to structured TE-mode RF cavities for future beam-manipulation studies.
