A New Double Counting Cancellation Technique for Three-Dimensional Ray Launching Method

A new efficient algorithm is proposed to avoid the ray double counting problem in the three-dimensional ray launching method. This new method is very simple and is based on the angle between the received rays and the total distance traveled by them. These two parameters have to be saved in every ray launching method and therefore the proposed method does not need any extra memory. Comparison between the simulation results shows the good performance of the proposed method
