Title:
METHOD AND SYSTEM WITH FRAGMENTED METASTRUCTURES FORMED WITH A PLURALITY OF METASURFACE ARRAYS
Document Type and Number:
WIPO Patent Application WO/2023/003961
Kind Code:
A8
Abstract:
An exemplary method and system are disclosed comprising retroreflective metastructures formed with a plurality of metasurface arrays configured to destructively cancel or interfere, in part, with one another to reduce specular mode associated scattering or reflection. In some embodiments, the retroreflective metastructures are formed by a combination of metasurfaces with different lattice spacings that can exhibit enhanced bandwidth and angular range at near-grazing angles to provide enhanced retroreflective electromagnetic responses.
