Popis: The design and absorption analysis of a unit cell of a new multiband split-S-shaped metamaterial is presented in this paper. The computer simulation technology (CST) software based on finite-difference time-domain method was used for the design of the unit cell and its S-parameter calculations. The proposed design shows the resonance frequency within the S-band, X-band, and Ku-band of the microwave spectra. In addition, the proposed material can be used in ε-negative, μ-negative, near-zero refractive index, and double-negative applications as well. The measured result is presented, which shows good conformity with the simulated result. The material shows nearly the same characteristics with bit shifted transmittance at the higher frequency side after reducing the coupling capacitance in the y- or z-axis of the proposed metamaterial. Moreover, it is evident from the investigation that, for shifting the lower ring in the z-axis, 15% more absorption can be achieved for the proposed metamaterial. The simple design, multipurpose applications, and compact size have made the design novel in the electromagnetic paradigm.
