The parabolic equation method,which is an efficient and fast numerical approach based on paraxial approximation of the wave equation,models energy propagation in a cone centered on the paraxial direction.

The rotated parabolic equation method was presented to compute the bistatic radar cross section(RCS).

Analysis of radio propagation in partly forested terrain environment using parabolic equation approach;

Analysis of radio propagation over rough sea surface with parabolic equation

Because atmospheric duct have a great effect on radio propagation,the technique of dealing with atmospheric duct is presented for inverse diffraction parabolic equation.

In this thesis the parabolic equation methods based on the higher-order Pade approximation are successfully applied to establish seismo-acoustic propagation model.

The parabolic equation method has been used widely in the electromagnetic wave propagation model and becomes the main tool to resolve the problem of electromagnetic wave propagation.
