Sensitivity Analysis of Possible THz Virus Detection Using Quad-Band Metamaterial Sensor

This paper proposes the method for detailed sensitivity analysis which is then demonstrated on the chosen quad-band metamaterial sensor used to detect the presence and the concentration of three different strains of Influenza A virus: H1N1, H5N2 and H9N2. The results show that metamaterial structure can be successfully used for detecting extremely low virus concentrations with relatively high sensitivity for all four resonant frequencies and, therefore, give significant contribution to the medical diagnostics. Presented approach can potentially ease the practical use of sensors and assure their best utilization in medical and other applications.
