【Abstract】 In view of the characteristics and problems of the teaching of electromagnetic field theory,this paper introduces COMSOL finite element software into the teaching of this course. In this paper,I choice the design of the cylindrical electromagnetic invisibility cloak as example,which is firstly proposed by Pendry based on the coordinate transformation. Then,this paper derives the formula of the cylindrical electromagnetic cloaking and how to realize this cloaking by using this finite element software COMSOL,so as to stimulate students’ learning enthusiasm and reach the purpose of improving the teaching effect of this course.更多还原
