A PROJECTIVE APPROACH TO ELECTROMAGNETIC PROPAGATION IN COMPLEX ENVIRONMENTS
2009
Progress in Electromagnetics Research B
High frequency methods resort to numerical ray tracing for application to complex environments. A new method based on the geometrical projection performed by a ray-congruence has been developed as a preconditioning of the ray tracing procedure. It builds a visibility tree, i.e., a database, storing information on all possible ray paths inside a scenario. The method gives a solution to a class of open problems of ray tracing techniques: ray missing, double (multiple) counting, termination
