The scattering of electromagnetic waves by bodies and particles with free surface charges

The problem of electromagnetic waves dispersal by bodies and particles on the surface of which there is a free surface charge is reviewed. For a plane border between two media with the free surface charges ratios are obtained to determine the coefficients of refraction and reflection, depending on the surface charge density. When the value of the surface charge density are directing to zero, they transfer to the well-known Fresnel formulae. It is shown that the presence of surface charge increases the reflection coefficient and decrease the transmission coefficient as compared with the uncharged surface.
