Sm. Apollonskii et Vt. Erofeenko, IMPEDANCE BOUNDARY-CONDITIONS FOR ANISOTROPIC BODIES, IEE proceedings. Microwaves, antennas and propagation, 142(2), 1995, pp. 89-92
Impedance boundary conditions for electromagnetic fields on massive bo
dies with anisotropic complex dielectric permeability are obtained. Fo
r isotropic bodies, if the electrical conductivity of a surface materi
al is sufficient, the boundary conditions can be transformed in Leonto
wich's conditions. Different forms of impedance boundary conditions ar
e shown here, as well as an example of calculation.
