to attenuate radiation from a polarized source.

to polarize radiation from an unpolarized source.

These features make them ideal for high quality projection systems, military applications, medical imaging, simulators and even digital cinema. Finally, they have greater thermal stability and can operate under high temperature or high flux conditions. They are also inherently broadband and can be designed to operate across UV-Visible-IR by choosing appropriate substrates. For instance, they are suited for applications that require a high ER. Wire grid polarizers offer several advantages over conventional polarizers.

A wire grid polarizer is typically characterized by the extinction ratio (ER) and polarization efficiency (PE). Hence, most of the p-polarized light is transmitted. In case of the p-component, electrons can only be excited along with wire width, which is in the sub-micron range.

As a result, the s-polarization is almost completely reflected. For the s-component, the metal grid works like a typical metal surface as electrons are excited along the wire length.

Fine metal wires typically 100 nm to several microns apart are lithographically deposited on substrates depending on the desired wavelength range. Wire grid polarizers are a class of polarizers that use fine metal wires to restrict E-field oscillation for s-polarized light.
