The first and second programs utilize a non-modal and model formulation, respectively, which are derived in detail in an earlier report. Some approximate solutions are available when the slit cross section is a rectangular shape and these are investigated in the third program. The programs are all written in Fortran IV language. Quantities computed are equivalent electric and magnetic currents on the contour defining the slit cross section, transmission coefficients, gain patterns, and normalized field patterns. Sample input and output data are presented for each program. Detailed instructions concerning the use of each program and its capabilities are given. (Author) 收起
