Computer programs for electromagnetic scattering from a slotted TM cylindrical conductor by the pseudo-image method

Two computer programs are described and listed. Suppose that an infinitely thin perfectly conducting cylindrical surface with an infinitely long but narrow gap is illuminated by a TM plane wave. The first program uses two different methods, the methods of solution with and without pseudo-image, to calculate the tangential electric field in the gap. The second program uses the Fourier series method of solution to calculate the tangential electric field in the gap for the special case in which the surface is a nearly complete circular cylindrical shell and the TM plane were propagates perpendicular to the plane of the gap. To enable the user to verify that they are running correctly, both programs are provided with sample input and output data.
