Over the past two decades, metamaterial absorbers have undergone significant advancements, evolving from microwave single-frequency designs to multi-frequency and broadband absorption, extending into the terahertz band. These absorbers have transitioned from unadjustable to adjustable and multifunctional configurations, enabled by the integration of adjustable materials, mechanical structures, and semiconductor devices. This article provides a comprehensive review of the progress achieved in the microwave to terahertz frequency range over the last five years. Key aspects covered include the absorbing mechanism of metamaterials in the microwave frequency band, with absorption efficiencies exceeding 90% for specific frequency ranges. The development of adjustable absorbers allows for frequency tunability within ±10% of the central frequency, while multifunctional absorbers enable concurrent control over absorption and reflection properties. In the terahertz regime, advanced electromagnetic simulations have led to absorber designs with bandwidths exceeding 50% of the central frequency, resulting in absorption efficiencies above 80% over the entire bandwidth. Integration of gallium nitride-based Gallium Nitride High Electron Mobility Transistors (GaN HMET) provides fast switching speeds below 100 nanoseconds, facilitating rapid reconfiguration of absorber functionalities. These advancements in metamaterial absorbers offer promising prospects for intelligent and integrated designs in future applications.

“…Taking advantage of VO 2 's phase transition properties, the device served two purposes in different frequency ranges: broadband absorption functionality (1.03 THz to 2.62 THz) and polarization conversion functionality (1.81 THz to 2.39 THz). 24 In 2024, Li et al suggested a tunable bandwidth absorber utilizing a monolayer of graphene. This absorber can attain absorption rates exceeding 0.9 within the 3-6 THz range.…”

“…Terahertz (THz) wave, in the range of 0.1THz-10THz, is a kind of electromagnetic wave, which is located between microwave and infrared light wave [1][2][3]. Many substances in the world can radiate terahertz wave, and the most of material information can be obtained through their terahertz spectra [4][5][6]. Moreover, THz wave has many excellent characteristics, such as large bandwidth, low quantum energy and high signal-to-noise ratio, which has great potential applications [6].…”

Tamm plasmon polaritons have super strong field localization, and can be directly excited by TM or TE polarized light without dispersive devices, whose related technology has become one of the research hotspots nowadays. In view of this, in this paper, a terahertz sensor device based on double-dip detection of Tamm plasmon polaritons is designed. The device is asymmetric structure, which can excite two Tamm plasmon polaritons modes with the different intrinsic energies at the interface between two DBRs and graphene. Through the optimized simulation analysis of its terahertz sensing characteristics, the results show that the reflection spectrum under this structure has two dips at 0.9THz and 1.0THz respectively, and their full widths at half maxima of 0.0361THz and 0.0131THz are relatively narrow. Moreover, their sensitivities are 0.21THz/RIU and 0.41THz/RIU, and the figure of merit can reach up to 5.69RIU−1 and 31.33RIU−1, respectively. Therefore, this research is suitable for high sensitivity terahertz double-dip detection, and has important application prospect in terahertz devices.
