DOI: 10.1016/j.ijleo.2020.165637
Abstract: Abstract The optical properties of four triatomic all-dielectric metamaterial structures composed of TiO2 media are investigated numerically. Two symmetrical metamaterial structures with dark-bright-dark coupling mode and bright-dark-bright coupling mode can enhance and cancel the original… read more here.
