The DNG structure unit is composed of square split ring resonator and strip wire. The modified NRW method is used to extract the equivalent permittivity, permeability, and refractive index from the scattering parameters of the two-port waveguide with DNG structure. At the designed operating frequency, the refractive index approximates zero, which makes the nondirective electromagnetic wave tend to approximate plane wave along the normal direction of the superstrate and congregate the radiation energy.
