US Patent 11249234 Polarizer with composite materials

It would be advantageous to improve polarizer high temperature resistance, corrosion resistance, oxidation resistance, optical properties, and etchability. Composite polarizer materials can be used to achieve this. A polarizer can comprise polarization structures configured for polarization of light. The polarization structures can include a reflective rib, the reflective rib being a composite of two different elements. The polarization structures can include an absorptive rib, the absorptive rib being a composite of two different elements. The polarizer can include a transparent layer, the transparent layer being a composite of two different elements.
