Abstract

The transmission of electromagnetic fields through corrugated slots is studied for TE and TM polarization. A corrugated slot means that the slot is formed by a gap between two plates and that the edge walls of one or both of these two plates have grooves or corrugations running in the direction of the slot. The field solution is obtained by using the method of moments implemented as a successive inversion of the matrices associated with the unknown E-fields at the apertures between the rectangular regions forming the corrugated slot. The computer code is applied to analyze slots with corrugated edges, where the corrugations or chokes are optimized in order to make the transmission as low as possible over a given bandwidth. The results are verified by comparison with previously published results and measurements on three different slot geometries
