Applications of the Field Transformation for Artificial Magnetic Conductors

Abstract

The Field transformation (FT) method provides a impedance control at any incidence angels, which makes it a superior method for wide-angle devices design. In this paper, a wide-angle artificial magnetics conductor (AMC) was designed by FT method and was numerically demonstrated. The theoretical FT medium was then approximated using the reduced parameter and experimental approximations, which maintains the AMC properties in a large angular range. The angular bandwidth of the proposed AMC is up to 50°.
