The study of many phenomena in the terahertz (THz) frequency spectral range has emerged as a promising playground modern science and technology, with extensive applications high-speed communication, imaging, sensing, biosensing. Many THz metamaterial designs explore quantum physics embedded into classical framework exhibiting various unexpected behaviors. For spatial waves, effects inspired by include electromagnetically induced transparency (EIT), Fano resonance, bound states continuum (BICs), exceptional points (EPs) non-Hermitian systems. They facilitate realization functional metadevices applications. on-chip physics-inspired topological metamaterials, photonic analogs insulators, can ensure robust, low-loss propagation suppressed backscattering. These trends open new pathways for data transmission integrated circuits, being crucial upcoming 6G 7G wireless communication technologies. Here, we summarize underlying principles metamaterials highlight latest advances their application band, encompassing both metadevice realizations.

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
