The emissivity of conductor Gaussian random rough surfaces: the surface impedance boundary condition method

We are interested in studying the contributions of the physical parameters of materials to the emissivity of random rough surfaces for both transverse electric and transverse magnetic waves. Comparisons between the surface impedance boundary condition (SIBC) and the exact results are presented. The effects of the incident angle, the material surfaces and random roughness on the directional emissivity are quantified. The contributions of the effects to the emissivity are used to investigate the domains of validity of the approximate model.
