Abstract :
An interactive circular-cylinder modeler software program in which the approximation of a complex scatterer is achieved by using circular cylinders is described. The cylinders are made of either homogeneous isotropic dielectric material, perfectly conducting material characterized by a surface impedance, or a combination of the two. The user interface is designed for quick construction of two-dimensional scatterers using circular cylinders of arbitrary radii. The algorithm for multiple scattering between these cylinders is based on the enforcement of the appropriate boundary conditions on the surface of each cylinder. The source of excitation can be a plane wave or a line source parallel to the scatterer, and both TM and TE types of polarization are considered
