Abstract:
The form of a quasi-optical equation for a beam of monochromatic radiation propagating through a layer of a weakly absorbing linear medium is analyzed. It is concluded that the standard form of this equation should be modified using an “effective diffusion coefficient.”
Keywords:
quasi-optical approximationá slowly varying envelope method, effective diffusion coefficient.
