OPTICAL MEMBER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240337891 titled 'OPTICAL MEMBER
The patent application describes an optical member with high reflectivity of electromagnetic waves in a desired direction for use in a metasurface structure. The optical member consists of a reflective layer, a liquid crystal layer containing a liquid crystal compound, and a metasurface structure with microstructures where the in-plane refractive index of the liquid crystal layer changes continuously based on the region of the metasurface structure.
- Reflective layer
- Liquid crystal layer with liquid crystal compound
- Metasurface structure with microstructures
- Continuous change in in-plane refractive index of the liquid crystal layer
- High reflectivity of electromagnetic waves in a desired direction
