Simulasi Struktur Metamaterial Resonator Cincin Pisah Heksagonal Untuk Aplikasi Pada Frekuensi 1 GHz – 120 GHz
Metamaterial simulation computationally is practice way for observing metamaterial which commonly achieves new metamaterial structures. This research investigates hexagonal-shaped metamaterial with gap and concentric double ring resonator, namely split ring resonator hexagonal-shaped (SRR-H). SRR-H metamaterial is optical metamaterial observing for frequency of 1 to 120 GHz. The simulation result shows that SRR-H has similarities with SRR circular- shaped. Variation of kind of materials were not changed the resonance frequency, but change in shape and size could changed the resonance frequency significantly. The resonance frequency tends to shift to the lower when the size was increased. Furthermore, structure type and gap orientation of the ring can change the resonance frequency. Electromagnetic parameters of the structure, such as permeability, permittivity and refraction index, has similar pattern because dominating of magnetic permeability. Metamaterial SRR-H has successfully demonstrated for negative index of refraction (double negative) and agreed with Lorentz’s model.
