This paper presents a comparison between a volume electric field integral equation (VEFIE) modelling approach and ray tracing for the purposes of indoor propagation modelling. Focus is drawn to the inclusion of multiple internal interactions in the computation of reflections and transmissions in ray tracing. Results are presented for lossless and lossy materials. It is found that including multiple...
This paper presents preliminary work done on developing a 3D full-wave indoor propagation model. The model is based on the volume electric field integral equation (VEFIE) which when discretised by a weak-form discretisation results in a dense linear system whose solution can be expedited through use of the Fast Fourier Transform and a reduced operator. A comparison between the current standard for...
