Backward reflection of an aluminum plate immersed in a liquid
Within the framework of electrodynamics of continuous media, a mechanism of backward reflection in bordering homogeneous media is proposed which includes not only the known modes (the reflected and the refracted ones), but also the backward-going modes. The equations of the backward-going wave are obtained. The coefficients of the backward reflection of layered media are determined. The results of measurements and the calculation of the back reflection coefficient of a smooth aluminum plate immersed in a liquid semiconducting medium are presented.
