Abstract
By introducing the curvature of the wave front in the ray model, we have developed Vectorial Complex Ray Model (VCRM) to describe the scattering of large and arbitrary shaped objects with a smooth surface. This model predicts correctly the divergence or convergence of a wave on the particle surface and the phase due to the focal lines. Thanks to this new property, the wave effect near singularity regions (rainbow, critical-scattering and forward diffraction) may be included directly. The fundamentals of VCRM and its extension – Ray Theory of Wave are presented in this communication.
