Electromagnetic scattering from arbitrarilyshaped lossy dielectric bodies
Abstract
The scattering properties of a twodimensional dielectric cylinder and a threedimensional dielectric body of revolution were studied using surface type integral equations and eigenfunction expansion. To test the validity of this method, homogeneous circular cylinders and spheres were first studied. The results thus obtained by the integral equation technique showed excellent agreement with the eigenfunction expansion solutions. Surface fields or currents on elliptical cylinders and conesphere bodies are presented to illustrate the applicability of the integral equation solutions to arbitrary geometries. Radar scattering patterns are then given for the above cylinders and bodies of revolution, as well as other structures. Field plots throughout the interior are also given for singlelayered and more complex cylinders. The surface integral equation technique can constitute a useful tool for pattern analyses and diagnostics of microwave hazards in biological tissues.
