New Approaches in Ray-Tracing and Boundary Element Method

Objective

An important difficulty of ray-tracing and boundary element method is the fine grid, which is needed in the high frequency region.

Method

By means of new alternating shape functions e.g. wavelets at the boundary it could be possible to define a grid on the boundary that is independent from the wave number.
