Estimation of losses per unit length in a rectangular waveguide with rough screening surfaces based on the concept of partial waves
Keyword(s):
A method for calculating the rough surface reflection coefficient of an electromagnetic wave is proposed. It is shown that the screening surface roughness in waveguides is equivalent to a decrease in conductivity of these surfaces in comparison with values belonging to Schukin-Leontovich boundary conditions for completely smooth surfaces. Examples of calculating the attenuation coefficient in the rectangular waveguide with rough screening surfaces in a terahertz frequency range are presented. The influence of the size and shape of the rough surface profile irregularities on the waveguide attenuation is studied.
