None sharp corner localized surface plasmons resonance based ultrathin metasurface single layer quarter wave plate

Abstract We report on a non-sharp-corner quarter wave plate (NCQW) within the single layer of only 8 nm thickness structured by the Ag hollow elliptical ring array, where the strong localized surface plasmons (LSP) resonances are excited. By manipulating the parameters of the hollow elliptical ring,...
