THE SCATTERING OF ELECTROMAGNETIC WAVES BY A FINITE WEDGE,

Abstract

The scattering of a plane electromagnetic wave by a perfectly conducting finite wedge and other cylindrical obstacles is solved for the case of symmetric excitation where the E field is parallel to the cylinder axis. Eigenfunction expansions for the field components are found using Green's functions. Through the application of boundary conditions, the problem is reduced to the solution of an infinite set of simultaneous equations for the scattered field expansion coefficients. These equations are solved by numerical methods. In addition, a perturbation solution is obtained for the reentrant wedge when the wedge angle is small. Finally, back-scattering radar cross-sections are calculated for various wedge angles and presented in the form of graphs.
