Abstract :
Improved site-specific prediction of the diffracted fields from lossy dielectric obstacles is presented. A commonly used set of diffraction coefficients are redefined in a more physical way. The theoretical basis for the improvement is presented and validation is given by comparison to full-wave simulation results
