Abstract :
High frequency methods resort to numerical ray tracing for application to complex environments. A new method based on the visibility map in a topological space has been developed as a preconditioning of the ray tracing procedure. The method allows reflected and diffracted contributions in a scene to be handled with an off-line electromagnetic field calculation. Some examples are provided showing the efficiency of the method
