Research on the Microwave Propagation in the Evaporation Duct with Obstacles
The influence of the microwave propagation in the evaporation duct is studied by solving wide angle parabolic equation using Fast-Fourier transform method. Then, the result under smooth surface is compared with the simple and complex obstacle on the surface. It is shown that the propagation loss of electromagnetic wave will increase in evaporation duct with increase of the propagation path and the height obstacle, which effectively improves its remote propagation in waveguide after diffracting.
