Abstract

Surface-plasmon resonance (SPR) sensors are widely used in different applications. In the present study, a noble electric field sensing is done theoretically by surface-plasmon resonance (SPR) phenomena using a multilayer structure. A glass prism is coated with a two metal (gold) layers sandwiched with lithium-niobate (LiNbO₃) material. The electric field is applied to the first and third layer of the metal. The measured electric field sensitivity is based on the angle interrogation and applied an electric field. The required mathematical expressions are included in this paper and the results are verified with the help of COMSOL multiphysics and MATLAB software.
