Abstract- In this paper, the simulation of light propagation of light with magnetic polarization in four-band plasmonic sensor for detection of industrial ammonia and urea is investigated. The nano-sensor is based on metal-dielectric-metal. The operation of the proposed sensor is based on exposure the sample with different refractive indexes, electromagnetic resonances is generated and the change of the peaks describes the mechanism for detecting chemicals material. The plasmonic metasurface have several advantages such as label free detection, nano-structure, suitable responsibility to chemicals material and good tunability. Simulation is investigated based on numerical analysis using CST.
Keywords: Electromagnetic Polarizat, Label Free, Plasmonic Metasurface, Tunability
