Description
Summary:Metamaterial application of hexagonal structures with two hexagonal ring-centered, hexagonal ring resonators (SRR-H) for frequency filter has greatly developed but in microwave frequency range. This paper proposes both higher frequency filter and energy. The SRR-H is designed and computed in the 300GHz - 300THz with outer and inner radii of SRR-H respectively for 0.5μm and 0.36μm to 0.35μm and 0.21μm. The simulation results show that the SRR-H size has an effect on the resonance frequency with the largest refractive index occurring at low frequency with the refractive index peak of -6.0242 corresponding to 9.765THz for SRR-H structure of outer and inner radius 0.4μm and 0.26μm.Resonance frequencies tend to shift at high frequencies when the geometrical size of the structure is reduced. This SRR-H filter can be used in THz frequency because the width of the resonance frequency occurs in SRR-H structure.
