Anteral’s Wire Grid Polarizers (WGP) consist of one layer of patterned Cu-Au micro grid array of strips. The micro grid array is patterned via photolithography process on very thin (135 µm) and ultra-low loss substrate for THz frequencies with low dielectric constant. The electric field is transmitted if polarized perpendicularly and reflected if polarized parallel to the grid array.
WGP are mounted with protection layers made of a high-performance polymethacrylimide foam without degradation of the quality.
The Polarizer can be used from DC up to 2 THz systems for enhancement of the polarization sensitivity, beam splitting
and generation of circular polarization.
Anteral also offers their Quarter Wave Plates for generating reflected circularly polarized waves from linearly polarized waves and Frequency Selective Surfaces with custom frequency performance.
