Abstract

An artificial engineered structure of nano-inclusion made of metallic nano-rods embedded in a dielectric (ε=12.96) matrix with hexagonal arrangement is proposed. New improved designed structure exhibits Negative Refraction (NR) in visible region by using surface plasmon wave in metallo-dielectric photonic crystal operating in a dispersion regime with anti-parallel refracted wave vector and Poynting vector. Finite Difference Time Domain (FDTD) simulations are carried out to study the reflection and transmission properties and obtained Far-field pattern. Designed structure gives NR with high transmission and act as a filter with a quality factor ≈ 10² with strong application potential in nano-optics and nano-technology.
