摘要

A formulation of the reflection and transmission of electromagnetic waves by a stratified planer structure is demonstrated. This formula uses the so-called elementary symmetric functions that are extensively used in the mathematical theory of polynomials. The reflection and transmission coefficients of any number of quantum wells or barriers can be written in a similar way. Finally. one-dimensional scattering from a series of delta-function barriers (it system that is called Dirac Comb) is investigated. An excellent agreement has been found with the earlier results based on other approaches. This approach is also shown to be a powerful technique and can be easily used for analyzing various complicated mesoscopic structures and devices. [References: 17]
