Abstract

The eigenpolarizations and resonant frequencies are derived for a circular dielectric waveguide resonator (EH₁₁ mode) terminated by perfectly reflecting metallic rooftop mirrors. It is demonstrated that, in the far-IR region, circularly polarized helical standing waves result from an arbitrary angular misalignment of the rooftop creases. Further, the right and left circularly polarized modes have different resonant frequencies.
