Multipath scattering by cylinders and spheres

Scattering problems with multiple canonical scatterers, like cylinders and spheres, may be modeled by utilizing the orders-of-scattering approach. This method provides an exact solution; however, being iterative in nature, the accuracy of the solution depends on the number of iterations; in other words, the number of higher-order scattered fields taken into account. The orders-of-scattering solutions were compared against the numerical solutions, obtained using a commercial software such as WIPL-D, and an excellent agreement is indicated. This technique has a potential for modeling dynamic multipath environments of multiple scatterers, such as those found in wireless communication environments, provided that the environment can be approximated by objects of canonical shape. The obtained results can then be compared with statistical models to shed more physical insight into the scattering process.
