Abstract: A dual-band terahertz metamaterial absorber with square cutouts and a windmill-like shape is presented in this paper. At 0.372 THz and 0.458 THz, respectively, the structure attains high absorption efficiencies of 0.96 and 0.99. 0.00271 and 0.00152 are the full width at half maximum (FWHM) values. The low-frequency absorption is explained by multireflection interference theory, and the results of simulations and theory agree well. Near-perfect absorption at higher frequencies results from magnetic resonance between the bottom metal layer and the patterned top metal. Applications like narrowband thermal emission, photonic sensing, and biosensing can benefit from the absorber's polarization-insensitivity.
