METAMATERIAL POLARIZATION CONVERTER

摘要

A polarization converter made of metamaterial, including a base material and a number of artificial microstructures disposed on the base material. The artificial microstructures can influence the electric field vector of plane electromagnetic wave propagating in it. The electric field vector of the electromagnetic wave can be decomposed into two non-zero orthogonal components on one or more planes perpendicular to the incident direction ofthe electromagnetic wave, the orthogonal components can be parallel and perpendicular to the optical axis at the position where the artificial microstructure located. After the electromagnetic wave passing through the polarization converter made of metamaterial, the two orthogonal components have a phase difference –³¸ different from before incidence, thereby achieving mutual conversion between the above electromagnetic wave polarization methods. The polarization converter made of metamaterial of the present invention is simple in structure, and can easily realize polarization conversion of electromagnetic waves.
