| Summary: | This work intends for sensitivity analysis of different metasurface array-based biosensors. The array designs in the form of circle array, square array, square circle array, circle square array, five-element square array, plus array, five-element plus square array. The sensitivity of these metasurface biosensors are compared and optimized design is presented. Circle array design shows the best sensitivity performance amongst them. The optimized circle array design is analyzed by varying different physical parameters of the design such as SiO2 substrate thickness and metasurface array thickness. The optimized results for this variation are also presented. The sensitivity of the current biosensor design is also compared with the previously published similar designs. The results are also presented for electric field intensity and current field density for the optimized design. The proposed sensitive biosensor can become a building block of future biomedical devices and photovoltaic devices. |
