In this work, an efficient field estimation technique is developed. This technique uses a single simulation of a ray tracing tool, at one spatial point at one frequency, to compute the field in the vicinity of the simulated point throughout a complete frequency range. The developed technique is a two-step procedure. Firstly, it operates over the images and field contributions generated by the ray tracing tool at the simulated receiver point to obtain an appropriate set of field contributions for each new receiver point. Secondly, once the new set of images and contributions at one frequency is obtained, a very simple extrapolation procedure is applied to obtain the electric field throughout a frequency range. The whole technique is computationally very efficient and it is also accurate, as the measurements comparison shows.
