ELECTROMAGNETIC SCATTERING FROM A RIGHT-CIRCULAR CYLINDER USING A SURFACE RADIATION CONDITION

The scattering of plane, harmonic electromagnetic waves from perfectly conducting right-circular cylinders is studied by making use of a sur face radiation condition. Using spherical polar coordinates, the surfa ce profile of the cylinder is described and the particular form taken by the surface radiation condition is determined. A numerical scheme i s outlined and the problems caused by the discontinuity of curvature a cross the surface are discussed. The results produced are then favoura bly compared with those produced by the numerical electromagnetics cod e and physical optics.
