Abstract
A large variety of simulation tools for calculating scattered fields have been published in literature. Basically, there are two main approaches, the socalled numerically exact or fullwave solutions, e.g. using Method of Moments (MoM), and the highfrequency or asymptotic solutions, e.g. using rays for modelling propagation paths. However, most of these simulation tools are limited to perfectly conducting surfaces or homogeneous dielectric bodies with ideally smooth surfaces. The present paper studies the enhancement of a ray tracing code based on the wellknown ShootingandBouncingRays (SBR) technique for calculating scattered fields of arbitrary objects, whose surfaces are characterised by roughness parameters.
