Abstract :
For a plane wave incident on a cavity-backed gap in a perfectly conducting plane, the coupled integral equations for the induced currents have been solved numerically and the far-field scattering computed. The results are compared with a quasi-analytic solution previously derived. For a narrow gap the agreement is excellent for all cavity geometries and for all material fillings that have been tested
