Electromagnetic wave scattering by a system of two spheroids of arbitrary orientation
Abstract
An exact solution to the problem of the scattering of a plane electromagnetic wave by a perfectly conducting arbitrarily oriented prolate spheroid is obtained by expanding the incident and scattered electric fields in terms of an appropriate set of vector spheroidal eigenfunctions. The incident wave is considered to be a monochromatic, uniform plane electromagnetic wave of arbitrary polarization and angle of incidence. To impose the boundary conditions, the field scattered by one spheroid is expressed in terms of its spheroidal coordinates, using rotationaltranslational addition theorems for vector spheroidal wave functions. The column matrix of the scattered field expansion coefficients is equal to the product of a square matrix which is independent of the direction and polarization of the incident wave, and the column matrix of the known incidentfield expansion coefficients. The unknown scatteredfield expansion coefficients are obtained by solving the associated set of simultaneous linear equations. Numerical results for the bistatic and backscattering cross sections for prolate spheroids with various ratio and orientations are presented.
