Fig. 2: Properties of multiple dielectric rods in the ENZ and non-ENZ hosts.
From: Dispersion coding of ENZ media via multiple photonic dopants
Configurations of (a) the two-dimensional (2D) non-ENZ host (εh = 0.5) and (b) ENZ host (εh ≈ 0) containing two square dielectric rods. The permittivity of ENZ medium is Drude dispersive, with the angular plasma frequency of ωp = 2π × 3 × 109 rad/s. Host areas in two cases are 0.33λp2 (λp is the free-space wavelength at ωp), while square rods D1 and D2 are chosen with the permittivity εd = 37 and side lengths of 0.122λp and 0.116λp, respectively. (c) and (d) are respectively the simulated transmission spectral response in non-ENZ and ENZ hosts, for different spacing s of dielectric rods. (e) and (f) are snapshots of the magnetic field distribution at the transmission zeros z and z’ for the cases of the non-ENZ host and ENZ host
