Abstract

A formula for evaluating the equivalent shunt admittance of an inclined slot in the narrow wall of a rectangular waveguide is presented. By using the infinite image array technique and the duality of electricity and magnetism

the difficulty involving the divergency of the series which is related to the dyadic Green’s function in the guide has been avoided. The computation problem of self reaction of the magnetic current outside the guide is also discussed. The numerical results show that good agreement between the theory and experiment has been achieved.
