Computer Code for Calculation of the Penetration of Electromagnetic Fieldsthrough Slots

摘要

The document describes the idea behind and the use of the PC computer codeCORRSLOT 1.0. The computer code is designed for calculation of the penetration of electromagnetic fields through a slot in an infinitely large and perfectly conducting ground plane. The slot cross section can, by the user, be defined as a number of subsequent rectangular sections. This capability makes it possible to perform calculations on corrugated slots. The exciting field is a plane wave with either TE or TM polarization and an arbitrary incidence angle. The theory for the calculation of the field penetration is based on an integral formulation and the numerical results are obtained by the use of the method of moments. Calculated quantities are the electric field distribution in the slot, the attenuation and the far field radiation pattern.
