A computer program is developed for the problem of transmission of electromagnetic waves from a rectangular waveguide into half space through a rectangular aperture. The aperture may cover all or part of the waveguide cross section, but the sides of the aperture are parallel to those of the waveguide cross section. The solution uses the moment method applied to the integral equation for the equivalent magnetic current in the aperture. The expansion and testing functions are triangles in the direction of current, and pulses transverse to the direction of current. Quantities computed are the equivalent magnetic current, the reflection coefficient and equivalent aperture admittance seen by the incident mode, and the radiation gain pattern. The computer program is described and listed with sample input-output data.
