High Performance Polarizer•

Very low transmission loss (< 1 dB)•High parallel isolation (> 45 dB)•Working bandwidth from DC to 1 THz•

Rotating frame with angular scale•

Ultra-low loss flexible and low dielectric
constant substrate material

Description
The Polarizer consists of two layers of patterned Cr-Cu-Au micro grid array of strips. The micro grid arrays
are patterned via photolithography process on each side of a very thin (100 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. Anteral High Performance Polarizer achieves a highparallel isolation below 45 dB from DC up to 0.6 THz and below 30 dB up to 1 THz, with very lowtransmission loss.

Applications
The Polarizer can be used from DC up to 1 THz systems for enhancement of the polarization sensitivity,
beam splitting and generation of circular polarization.
Circular polarization is generated for 45 degrees incidence by means of selecting the appropriate dielectric
thickness and backing the polarizer with a metal plate. Several thicknesses of the dielectric material can beselected for creating circular polarization between 50 GHz and 1 THz.

Additional Notes
Polarizers are provided in regular diameters of 50 mm and 25 mm. They are mounted in rotating frameswith angular scale of step equal to 1 degree and with ISO M4x0.7 connection.
Different sizes (up to 70 mm) and geometries (square and circular) can be provided according to customer
requirements. Ad-hoc frames for special purposes are also offered.
Polarizers are mounted with protection layers made of high-performance polymethacrylimide foam without
degradation of the quality.
The performance of all polarizers is checked before delivery.
Extended performance datasheet is available if customer requires. Ask for more information.
