摘要

A novel designing subwavelength resonator loaded with metamaterials has been investigated both analytically and numerically. Based on constitutive equations of DNG materials modeled by Drude model, the updated equations in the DNG materials are deduced and determined with the FDTD scheme. In the one-dimensional case, a subwavelength cavity resonator with metamaterials of negative permeability and negative permittivity is proposed. Numerical results show that the resonator with DNG materials has two resonances: one is a normal resonance; the other one is a subwavelength resonance. The proposed subwavelength resonator overcomes the diffractive limitation. By analyzing the numerical results, the physical dimensions of the subwavlength cavity resonator with operating in the subwavelength frequency can reduce to 0.083 times the operating wavelength in comparison to 0.5 times the operating wavelength for the conventional resonator. A new avenue has supplied for manufacturing the subwavelength resonators.
