New Compact Perfect Metamaterial Absorber for Dual Band Applications
A new multi-ring hexagonal with meandered line design structure based on simple outline is proposed for dual band application in microwave ranges. The finite-difference time-domain (FDTD) method based CST simulator was approved to examine the perfect metamaterial absorbance (PMA). The structure revealed the resonance frequency within the C-band and X-band of the microwave spectra. At resonance frequencies, the absorbance’s pinnacles are 99.18% at 7.96 GHz and 99.50% at 11.62 GHz, correspondingly. Dual band operating frequencies have been obtained by design configurations. The dimension of the offered structure is 10.50 mm × 10 mm × 1.6 mm that comprises all geometrical parameters to suitable the structure inside the area of substrate material. The results of the offered PMA exhibited dual band absorber response over the frequency ranges from 5 to 14 GHz. Therefore, the offered structure enables numerous application areas, for example, satellite communications, radar, security, protection as well as stealth innovation.
