Abstract

We present and analyze unique phenomena of enhanced transmission through systems of subwavelength dielectric cylinders embedded in an epsilon near zero host. Our analysis shows that these phenomena are due to Mie-resonance modes arisen in the dielectric cylinders. Subwavelength waveguides and lenses are proposed based on coupling of these modes between neighboring cylinders. Finally, the proposed phenomena and their possible applications are numerically demonstrated in the THz regime in a realistic polaritonic material of LiF rods in KCl. DOI:10.1103/PhysRevB.87.155130
