All-dielectric metasurfaces offer unconventional optical functional behaviors for manipulating light. due to the strong localization of light with negligible dissipative loss. Here. we propose a compact design for a light emission cavity consist of an all-dielectric grating reflector and an all-dielectric symmetry-breaking metasurface supporting “dark” mode. https://safeersappliancers.shop/product-category/bosch-cmg656bb1b-built-in-compact-oven-with-microwave-black/
