Abstract

we considered a layered structure based on one dimensional photonic crystals consisting of alternating layers of silica and air, as well as a cavity is coated by superconducting nanocomposites based on Bismuth. Using the transfer matrix method, we investigated the transmittance spectrum of the structure. We showed that in the transmittance spectrum of the proposed structure, clear resonant modes can be found for each of the different brain tissue samples, whose positions depend on the structure parameters, for example, the filling factor. Therefore, the study of the proposed structure as a biosensor for brain diseases can be useful in the design of sensing devices. By optimizing the parameters and using Bismuth-based high-temperature superconducting materials (BSCCO), we increased the sensitivity of the proposed structure, for example, for a type of brain disease called Lymphoma to .
