INTERACTION OF ELECTROMAGNETIC WAVES WITH INHOMOGENEOUS MEDIA HAVING NEGATIVE ELECTROMAGNETIC PARAMETERS

摘要

The problem of oblique transmission of an electromagnetic wave through a layer with helical structure (HS) is solved. Features of the diffractional reflection (DR) are analyzed. In the case of negative electromagnetic parameters (NEP) the inverse selectivity of the DR to the polarization is explained. The calculation of a storage on a HS based on a MgFj crystal in the frequency range of NEP is performed. The possibility of diffraction of optical range waves on periodical inhomogeneities of a crystal in the presence of NEP is shown.
