Metasurfaces. ultrathin two-dimensional arrays of artificially engineered meta-atoms. can impart spatially varying changes towards the incident electromagnetic wave and provide versatile functionalities once unprecedented in sub-wavelength thick natural materials. The wavefront manipulation by metasurfaces usually arises from the strong resonant behaviors of varied meta-atoms in subwa... https://allfixelectricales.shop/product-category/spst-6volt-relay/
