Electromagnetic Polarization Converttion by Multilayered Structure of Metal-dielectric Films on Optical Wave Band

摘要

Based on the effective medium theory, anisotropic microwave materials have been realized by a multilayered structure of alternating films. The equivalent material constitutive tensors have been calculated with different film orientations. The prevenient analysis shows that the structure can realize electromagnetic polarization splitter by controlling the orientation of the films on optical wave band. In this paper, the futher research on the structure shows multilayered structure of metal-dielectric films has property of electromagnetic polarization converttion by controlling the plane of incidence. This may lead to new ways of exploring novel polarization converttion materials and structures.
