A modified wave propagation model based on Gaussian beams tracing

Due to diffraction and receiving sphere leading to increased complexity for traditional ray tracing models, a novel wave propagation prediction method based on Gaussian beams tracking technique is proposed in this paper. The source field is firstly expressed by a superposition of shifted and rotated Gaussian beams by the Gabor frame decomposition. Then, the effects of reflection, refraction and diffraction can be evaluated easily by geometrical optics and the uniform geometrical theory of diffraction. So we can predict the field-coverage values at any point in a straightforward manner without reception sphere. The simulation results show that the proposed model has a good agreement with the measured data and is more efficient and convenient than other methods.
