In this paper the response of electromagnetic waves propagation in plasmonic structures composed by metals and dielectrics has been numerically analyzed. Thermal-optical coefficient was considered to demonstrate that the optical properties change the behavior of the structure at visible and infrared frequencies. The structure is composed by alternated thin layers of metal and semiconductor. The materials used in simulations are Silver for metal, Silica and Silicon for the semiconductors. Under temperature variations, these materials change their properties, like refractive index and can affect optical properties like absorbance, transmittance and reflectance. Besides, the incident angle was considerate as a variable. The Finite Element Method has been used to carry the simulations.
