An adaptive beam division for a visual simulation of high frequency electromagnetic wave propagation

We propose an adaptive beam division method for a visual simulation of high frequency electromagnetic wave propagation. In order to guarantee the correctness of visualization and calculate electromagnetic wave power within beam (transformation from beam data to volume data) with low computational cost, an adaptive beam division technique is introduced into the beam data structure. By implementation of the proposed method, one can transform beam data to volume data more correctly with lower computational cost and visualize the high frequency electromagnetic wave propagation by a so-called ray-casting algorithm, which is one of the most useful methods in computer graphics.
