Arbitrary voxel selection for speeding up a ray tracing-based EM simulator

The asymptotic methods, inverse 3D deterministic Ray Tracing (RT) models are characterized by an accurate prediction of the electromagnetic field both in the case of an outdoor as well as an indoor scenario. For Radio Frequency (RF) system planning, the RF coverage analysis uses the RT propagation model and the data of the scenario to predict the e. m. field distribution radiated by a transmitter (Tχ).
