New developments in energy efficient wireless communications systems and indoor location and tracking algorithms have created a greater demand for accurate propagation models. In this paper a frequency domain full wave propagation model is used to produce accurate power delay profile information. The propagation model is based on the volume electric field integral equation (VEFIE). The VEFIE is solved...
A hybrid model for the efficient and accurate computation of 3D indoor propagation is presented. The model is based on the volume electric field integral equation. Two 2D simulations with 3D components are performed and their results averaged to produce an accurate approximation for the total electric field. Numerical results are presented demonstrating the improved computational efficiency of the...
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...
The efficient approximate extension of a 2D integral equation formulation to 3D for the case of indoor propagation modelling is investigated. The method is based on the volume electric field integral equation discretised by the Method of Moments. Numerical results are presented which demonstrate the improved computational efficiency of the method when compared with a full 3D integral equation model.
This paper presents initial efforts to develop a full-wave propagation model for indoor electromagnetic wave propagation based on the Volume Electric Field Integral Equation which when discretised by the Method of Moments results in a linear system whose iterative solution can be expedited through use of the FFT. Although the formulation requires the discretisation of the entire volume, only unknowns...
This paper presents initial efforts to develop a full-wave propagation model for indoor electromagnetic wave propagation.

Two integral equation formulations for the analysis of two-dimensional indoor EM wave propagation are discussed in this paper. The volume and the surface electric fleld integral equations are discretised by the Method of Moments, resulting in dense linear systems whose iterative solutions are accelerated by using acceleration techniques. Numerical results are presented to compare the performance of...
