A theoretical model is defined for an electromagnetic pulse EMP simulator for testing EMP effects on high altitude satellites. The simulator is composed of three flat-plate transmission line sections. The first and third sections are tapered to accommodate, respectively, a generator and a terminating resistor. This problem is analyzed in the frequency domain over those frequency components which are known to contribute most significantly to a typical EMP waveform. The analysis uses a numerical technique to solve the basic problem of an unknown current distribution on a curved, tapered strip, excited by a known electric field. The unknown current is solved by the method of moments, using triangular basis functions. To check the computer program, input impedances are computed for the triangular dipole. It is shown that these solutions compare quite favorably with experimental results. Variations in the solutions are also demonstrated for these same cases when edge singularities are not taken into account in the analysis. Modified author abstract
