Polarimetry radar calibration using trihedral corner reflectors with electromagnetic band gap polarization converters

Polarimetric radar systems need calibration. Trihedral corner reflectors are used for calibration. Conventional techniques cover one side of the reflector with corrugations which are heavy and thick. In this paper an electromagnetic band gap material is designed to cover one side of the reflector. The electric field incident upon the reflector is linearly polarized. The reflected electric field is also linear but perpendicular to the incident field. These materials are low profile, low cost , broad band and simple to construct.
