Scattering of Electromagnetic Radiation by Apertures; 1. Normal Incidence on the Slotted Plane,

Abstract

The results of the first of a series of investigations into the diffraction of electromagnetic radiation by apertures in conducting screens are reported. Calculations of the fields everywhere for linearly polarized plane electromagnetic radiation normally incident on a slotted conducting plane are given. Although this problem has been solved by others earlier, it serves as a useful application in that it provides a test of our method of solution. Comparison of the work with the standard solution shows indeed that the technique yields results in excellent agreement with those in the literature. Results were obtained by a technique of approximation in which infinite series representations of the fields are systematically truncated by utilizing the device of applying the usual boundary conditions but only at selected points of the boundaries. In this work the mathematical boundary used is one constructed in a manner convenient to the geometry of the diffracting system in precisely the same manner that had been shown earlier to be highly useful in static problems.
