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.
