Description

The radiation from a source in the presence of a convex surface can be found using GTD/UTD methods when the dimensions of the object are more than one or two wavelengths. The major problem is finding the geodesics on the surface along which the rays travel in the shadow and transition regions. The method adopted is based on the Runge-Kutta integration method and has high accuracy.
