Abstract. Three variants of impedance boundary conditions in
case of plane wave incidence on interface between air and dielectric are
examined. Parallel and perpendicular polarizations
are considered. In given boundary conditions the surface impedance of
the second medium is taken equal to impedance in case of: normal incidence
(Leontovich-Schukin IBC), incidence at an Brewster angle, grazing incidence. Angular dependences of reflection coefficient
magnitude error of all IBCs and dependecies of
maximum absolute error of reflection coefficient phazor from imaginary part
of complex permittivity are studied.
Keywords: plane electromagnetic wave, parallel and perpendicular polarizations,
reflection, dielectric halfspace, impedance boundary conditions.
