Design and Analytical Evaluation of a High Resistance Sensitivity Bolometer Sensor Based on Plasmonic Metasurface Structure

The bolometric effect (BE) allows to electrically monitor spectral characteristics of plasmonic sensors, but trade-off between sensitivity, response time, and strong light absorption is an important challenge. Here, the BE for a high resistance sensitivity sensor proposed studied based on multilayer structure at 26 °C. By generating coupling incident wave surface plasmon polaritons (SPPs), very narrow spectra with figure merit (FoM) achieved, that heats silver thin film, leads variation in temperature supports TE mode. rectifies metal film by BE. Optical metasurface bolometer (MBS), are calculated TMM 3D-FDTD, maximum quality factor 17.2 RIU -1 , 530 FoM 434.5. Finally, we analytically simulate coefficient terms wavelength refractive index analyte can be monitored external electric model. thermal, optical, MBS used biophysics, biology, environmental science because its compact footprint comparison any previous reports.
