In recent years, the computational electromagnetics community has witnessed a rapid increase in the electrical size of scattering problems that can be solved. This increase can be mainly attributed to the use of boundary integral equations and the development of the multilevel fast multipole algorithm (MLFMA) and its parallelized analogues. However, many challenges remain, especially when it comes...
A fast modeling of the wave propagation inside a rectangular room surrounded by walls of arbitrary thickness was presented. The solution was based on derivation and evaluation of the Green's function for the separable rectangular room, obtained by separation of variables method. The results for the test cases showed a good agreement when compared with the results obtained by the ray tracing technique.
The tool has been tested on several scenes with increasing complexity and the corresponding computational cost has been evaluated, confirming the expected speed and accuracy. The extensive testing has also shown that a deeper optimization of the code can further increase its performances. Improvements are expected by compressing the Beam Output File. While changes to the geometry data structure and...
