Abstract
Electromagnetic transmission through an annular aperture surrounded with corrugations in a PEC plane is investigated based on the mode-matching method. The eigenfunction expansion and Hankel transform are utilized to represent the scattered field in the discrete and continuous modes. We demonstrate that a new type of extraordinary electromagnetic transmission can occur due to the strong excitation of TM11 mode even if the corrugation is wide, as well as finding the optimal dimensions based on the three-dimensional parametric study.
