PLANE-WAVE SCATTERING BY AN ARBITRARY CROSS-SECTIONAL CYLINDER

A new technique for solving the scattering of a plane electromagnetic wave by an arbitrary cross sectional cylinder is presented. The techni que is based on solving the problem of multiple scattering of a plane wave by N thin strips as a boundary value problem. Then, by simulating the boundary of the cylinder by a sufficient number of strips, the to tal scattered field can be calculated. The technique is applied first to some of the known cylindrical geometries to check its acuuracy, whi ch is found highly accurate. The technique is also useful for calculat ing the scattered field of large cylinders, of known cross sectional a rea, where the exact solution is not rapidly convergent. Moreover, it has an advantage over other numerical and simulation techniques for pr oblems involve sharp edges where this technique automatically accounts for the edge diffraction.
