Abstract : Examples that demonstrate theoretical methods for extending the operating power levels of metasurface reflectarrays have been given. The proposed designs provide the same utility that has been previously demonstrated, however are capable of operating at much higher power levels. Future Work: Investigate additional electrically-tunable alternatives. Demonstrate mechanically tunable reflect-array metasurface. Fabrication and testing of a static prototype with predetermined super cell heights to form gradient phase distribution producing a desired reflected beam. Investigation of mechanical systems capable of reconfiguring ground plane without significant performance impacts.
