Abstract :
The question of obtaining the solution of an open-region (OR) problem from the limit of the solution of a related closed-region (CR) problem is investigated. An artifice based on using impedance surfaces is introduced to improve convergence of the CR solution to the OR solution. Computer results pertaining to the problem of radiation from an open-ended parallel-plate waveguide are presented.
