Abstract<\/b><\/h5>\n
The biosensor capable of detecting COVID-19 (SARS-CoV-2) viruses in the terahertz (THz) regime has the potential <\/span>to revolutionize virus detection and diagnosis. One effective<\/span><\/h5>
approach is the utilization of a new type of sensor called a multi-band metamaterial. These metamaterials are artificially <\/span>engineered materials that exhibit properties not typically found <\/span>in natural substances. They consist of sub-wavelength structures <\/span>designed with precise electromagnetic properties. Multi-band <\/span>metamaterial sensors can simultaneously detect multiple frequencies <\/span>of THz radiation, increasing the likelihood of virus detection. <\/span>These sensors offer several advantages, including high sensitivity,<\/span><\/h5>
non-destructiveness, and the ability to accurately detect even small amounts of virus particles. Consequently, they enable faster <\/span>and more accurate diagnoses of COVID-19 (SARS-CoV-2). In the <\/span>THz regime, the biosensor employs a novel multi-band metamaterial <\/span>resonator that incorporates a thin gold layer (35nm). The <\/span>resonance frequency and parameter S11 (dB) of the sensor exhibit <\/span>sensitivity to changes in the refractive index of the sample. This <\/span>sensitivity allows for precise and reliable detection. The study<\/span><\/h5>
demonstrated that our sensors exhibit minimal frequency offsets, compact electrical dimensions, high sensitivity, and a linear relationship <\/span>between the sensor\u2019s resonant frequency and refractive <\/span>index, enhancing their effectiveness. The proposed structures have <\/span>demonstrated the ability to detect COVID-19 viruses with an average <\/span>sensitivity of 347.7GHz\/RIU (2.154dB\/RIU). This biosensor <\/span>can differentiate between different types of COVID-19 viruses, <\/span>further highlighting its potential in virus identification and classification.<\/span><\/h5>\n
