Abstract:
The purpose was to analyze the different power given off by a cell phone for every type of ray. A cell phone's ray can be direct, reflected, refracted, double-reflected, double-refracted, and any combination of these things. By analyzing the power of all the different rays, we hoped to help in the progress to developing a more effective cell phone. The process for achieving the goals was complicated. First a script for virtual cities in a .dxf file had to be written in Notepad. Then, a program written by Professor Dandekar was run to create a simulation of a cell phone at different points of the city. It was uncertain if the power contributed by the double-reflected and double- refracted rays was significant enough to spend time calculating. A program was written to evaluate the power given by each type of ray. An analysis of the data showed the results and contribution of all the types of rays.
