Given the recent success of metasurfaces in free-space applications. these concepts can be leveraged to an even larger extent in on-chip waveguide systems. The in-plane diffractive metasurfaces enable the manipulation of guiding waves in the multimode regime with greater parallelism than conventional single-mode or few-mode waveguides. leading to exciting opportunities in signal proce... https://megavitamines.shop/product-category/colon-care/
