We propose a temperature-tunable and dual-broadband switchable coherent perfect absorber (CPA) composed of an annulus-disk-shaped InSb pattern complementary graphene layer. By controlling the Fermi level graphene, temperature InSb, or relative phase incident beams, working frequency absorption CPA can be continuously adjusted. For energy 0 eV, dual-band absorptivities exceed 99%. The designed structure achieves broadband absorptance over 90% in range 0.145 THz to 1.24 THz, with bandwidth about 158.12% for 0.5 eV. Moreover, temperature-dependent permittivity enables thermal tuning region. Furthermore, by altering input absorptivity varied between less than 1.2% more modes. Additionally, exhibits insensitivity polarization angle within 0° 90°. Therefore, this multifunctional holds significant potential applications modulation, sensing, all-optical switches, photodetectors.

Metamaterials (MMs) enable the manipulation of terahertz (THz) waves, which are vital for numerous applications due to their unique spectral fingerprints, non-ionizing nature, sensitivity weak resonances, and strong penetration through non-polar materials. However, detecting minor disturbances subtle features in biological chemical sensing is challenging when object’s scale smaller than THz wavelength. This limits development bio-chemical detection technology. MMs offer a solution, with recent research combining these materials new structures mechanisms enhance sensitivity. article reviews progress sensing, focusing on key performance parameters like spoof surface plasmon polaritons (SSPPs), bound states continuum (BIC), electromagnetically induced transparency (EIT). It explores future directions biomedical diagnostics, non-destructive testing, security, environmental highlighting transformative impact
