Analyzing the Frontier scientific issue applying Classical Separation Variable Method

摘要

In this paper, we introduce surface plasmons, a hot issue in the Frontiers of Science and Technology into the teaching process of "Mathematical Physics Method" course. We analyzed extensively metal nanowires, a typical plasmonic waveguide combining the separation method and numerical solution method. Dispersion Equation of guided modes by Metal Nanowires and Electromagnetic Field are investigated. On this basis, the single-mode transmission conditions of metal nanowires and the mode size of the fundamental mode are analyzed. Our practice has proved that this kind of teaching methods integrating the frontier of science and technology is of great significance to improve students' learning interest, arouse students' initiative and creativity in classroom learning, and cultivate their ability of scientific research and innovation.
