Abstract

Electromagnetic radiation from a circular cavity with multiple circular apertures in a conducting plane is investigated. An electromagnetic boundary-value problem of the circular cavity with circular apertures is solved based on the Green´s function, integral transform, superposition, and mode matching method. The radiated fields from the circular cavity are calculated in terms of the aperture geometry to understand the radiation behaviors and measured to check the validity of our theoretical formulations.
