Anteral offers polarizers that operate at MmW and THz frequencies with low transmission loss and high parallel isolation. Two different models are in stock, both of them are mounted in rotating frames with angular scale and clear apertures of 50 mm and 25 mm.
Anteral Wire Grid Polarizers consist of a simple pattern Cr-Cu-Au micro grid strip-array. This micro grid array is patterned following a photolithograpy process on a very thin (100 µm), ultra-low loss and flexible substrate for THz frequencies with low dielectric constant. The electric field is transmitted when polarized perpendicularly and reflected when polarized parallel to the grid array.
These polarizers can be used in MmW and THz systems in order to enhance the polarization sensitivity, beam splitting and generation of circular polarization.
