Abstract :
Electromagnetic radiation from a cavity-backed circular aperture surrounded by corrugations is investigated. An electromagnetic boundary-value problem of the cavity-backed circular aperture surrounded by corrugations in a conducting plane is solved based on the Green´s function and mode matching method. The radiated fields are computed in terms of corrugation geometry to illustrate radiation behaviors and measured to validate the computation.
