“…Based on the basic principle of SRR metamaterials, some researchers tried to make some detailed discussions about mechanisms and prospects by simulation. Saxena and Daya built a theoretical model of concentric square ring with the biological material and made the simulation to study the property of this biological material through computer simulation technology microwave studio [ 158 ]. Wellenzohn and Brandl built a simulation model by using the finite element method and designed a novel structure-Cu/FR4/Cu/Ni/Au to detect permittivity changes in the bio-layer [ 159 ].…”

Early cancer diagnosis and treatment are crucial research fields of human health. One method that has proven efficient is biomarker detection which can provide real-time and accurate biological information for early diagnosis. This review presents several biomarker sensors based on electrochemistry, surface plasmon resonance (SPR), nanowires, other nanostructures, and, most recently, metamaterials which have also shown their mechanisms and prospects in application in recent years. Compared with previous reviews, electrochemistry-based biomarker sensors have been classified into three strategies according to their optimizing methods in this review. This makes it more convenient for researchers to find a specific fabrication method to improve the performance of their sensors. Besides that, as microfabrication technologies have improved and novel materials are explored, some novel biomarker sensors—such as nanowire-based and metamaterial-based biomarker sensors—have also been investigated and summarized in this review, which can exhibit ultrahigh resolution, sensitivity, and limit of detection (LoD) in a more complex detection environment. The purpose of this review is to understand the present by reviewing the past. Researchers can break through bottlenecks of existing biomarker sensors by reviewing previous works and finally meet the various complex detection needs for the early diagnosis of human cancer.

“…The general process of measuring the dielectric properties or refractive index of materials (gas, liquid, or solid) is to calculate and quantify the interaction of these materials with electromagnetic waves. 23,24 Therefore, metamaterials/metasurface sensors have the advantages over other types: small size, low energy consumption, high sensitivity, and easy integration. Moreover, using a metamaterial/metasurface chemical sensor can achieve non-contact measurement of material properties (including dielectric constant, refractive index, conductivity, magnetic permeability, etc.).…”

Optimized absorption performance of a terahertz single mode metamaterial for gas and liquid detection

Metamaterial absorbers are widely used in the sensing field based on their rich resonance behaviors. So far, the applications of metamaterial absorbers in gas sensing have not been paid much attention by researchers. A single-mode narrow bandwidth THz metamaterial absorber is suggested and validated. An absorption peak is excited based on local surface polarization mode resonance and dielectric loss in the 2 to 36 THz band. In experiments, the hole array diameter R is increased, the absorption peak is increased from 0.51 to 0.66, and resonance position is moved to the high-frequency region. When the dielectric layer thickness h 2 is increased, the absorption peak is increased from 0.51 to 0.57, and resonance position is moved to the low-frequency region. Similarly, when the dielectric layer thickness h 3 is increased, the absorption peak is increased from 0.51 to 0.53, and resonance position is also moved to the low-frequency region. This metamaterial absorber exhibits the feasible for gas and liquid sensing.

“…Because the permittivity and permeability of electromagnetic metamaterial absorbers can be controlled by artificially designing them, [1,2] they have attracted the attention of many researchers in the fields of radar antennae, [3,4] electromagnetic stealth, [5,6] lenses, [7,8] biological detection, [9] sensor technology, [10,11] and so on. In 2008, Landy et al [12] first presented a perfect metamaterial absorber, and since then metamaterial absorbers have made great progress.…”

Herein, a polarization-insensitive and wide-angle characteristic ultrabroadband metamaterial absorber (UBMMA) is reported, which covers the entire X band and Ku band and parts of the C band and K band. The standard unit cell of the UBMMA is designed based on the frustum of a cone with a through-hole, and it is composed of multiple metal and dielectric layers by cross. The calculation results indicate that the absorptivity of the proposed UBMMA is more than 85% from 6.65 to 23.73 GHz except for the frequency bands 13.10-13.20 and 15.38-15.73 GHz, and the absorptivity is more than 90% in the frequency bands 6. 65-12.25 and 20.33-23.33 GHz. The distributions of the electric field, magnetic field, and surface current are calculated and analyzed, and the absorbing mechanism of the UBMMA is explained. The UBMMA is insensitive to the transverse electric and transverse magnetic polarization, and it displays an agreeable absorption effect under high incident angles. The influence of important geometric parameters on the absorption performance of the UBMMA is studied. Because of the satisfactory ultrabroadband absorption performance of the UBMMA, it can be applied in the fields of satellite radar, broadband antennae, and electromagnetic shielding.
