Title The analysis of the reflection and refraction of electromagnetic waves in media

Abstract Based on the boundary conditions of Maxwell's equations and the basic law of the electromagnetic wave, the coefficient of refraction and reflection for the parallel polarized waves and the vertical polarized waves in media was deduced , the simulation result of the coefficient of refraction and the coefficient of reflection when changing the incident angle was given。 In addition, the propagation characteristics for the polarized waves in three-layer medias was analyzed with the equivalent wave impedance, the total coefficient of refraction and reflection for the vertical polarized waves was deduced when the

incident angle is between 0° and 90° in Multilayered dielectric media with the field analysis method,Finally, the result of simulation was given in three-layer medias。
