A high contrast grating-based surface Plasmon resonance-based biosensor with high detection accuracy has been proposed. High sensitivity has been obtained by using a high value of dielectric material. The detection accuracy and sensitivity are optimized utilizing the metal layer thickness and its width in the continuation of periodic gratings. With the help of the finite difference time domain (FDTD), the enhanced values are obtained and compared to the photonic crystal waveguide and surface plasmon resonance sensor. The proposed sensor also overlaps the fabrication constraints of various metals as a high value of dielectric material has been employed.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
