  The rapid and precise detection of viral aerosol has received considerable attention to prevent airborne diseases. In these days, coronavirus disease and its detection has become a common subject in the worldwide. The study is proposed to the detection of viral aerosol by surface plasmon resonance techniques. In this paper, design and optimization of a surface plasmon resonance sensor based on polymer optical fiber for detection of noval coronavirus is theoretically presented and validated. Here, S-glycoprotein antigen is considered as the marker of covid. The dependency of resonance wavelength of surface plasmon sensor on numerical aperture and refractive index of optical fiber is obtained using ray approach. It is observed that low refractive index core and high numerical aperture of optical fiber waveguide provides the better performance to the detection of vira.. Read More»
