A Diffraction Analysis of the Elliptical Reflector
Abstract
A study has been made of the distribution of the electromagnetic fields diffracted by an elliptical reflector that is fed by a source at or near one of its two foci. For both the elliptic cylinder and the ellipsoid of revolution, the following calculations have been made: the magnitude of the fields near the foci, the size of the focal region, the displacement of the focal spot as a function of the source displacement, and application of the method of stationary phase in calculating the fields at points distant from either focus. Explicit results are presented for the fields as a function of the eccentricity of the ellipse and the angles subtended by the reflector edges.
