Abstract :
A new triangular-grid ray tracing (TGRT) method is proposed. It is based on dividing the propagation region into triangles. The number of triangles is decided by the number of vertices of the structures, instead of their dimensions. For the 2D case, it can decrease the visible decision calculation to two edges for each triangle. It is shown that this method unifies the indoor and/or outdoor propagation problems and provides savings in computational time
