Abstract The analogy between the solutions of Schrodinger equation with Helmholtz equation in a dimension is established, mainly of particle propagation (electrons) on quantum wells, with the propagation of electromagnetic waves (light) among electrical means. When transmission phenomena are studied in layered media, wells or dielectrics, they are found in analogical results. In this work, it is first presented the transmittance for quantum case and electrodynamic case independently. Then, the scattering amplitudes are related in both cases (electrons and waves), describing the connection and representation between these two systems. Finally they are compared with the experimental results in the transparent zone (low-absorption 800-2500 (nm)) of ZnSe thin film transmission spectrum, making use of the Transfer Matrix Method (TMM).

Keywords : Waves; thin film; well and barrier potential; dielectric; transmission coefficient; education.
