电磁场与电磁波课堂教学融入科研内容的实践

Adding scientific research content in the classroom teaching of electromagnetic field and electromagnetic wave

电磁场与电磁波教材中讲授的都是不携有轨道角动量的传统意义上的电磁波,而携有轨道角动量的涡旋电磁波是当今研究热点.涡旋电磁波能实现在一个频带内传输多路信息,在不增加系统带宽的条件下极大程度地提高系统容量.在传统电磁场与电磁波课堂教学中融入涡旋电磁波科研内容,提高了教学的广度和深度,能够激发学生的求知欲,培养学生的科研思维.

In the course of electromagnetic field and electromagnetic wave, the contents of curriculum wave teaching are focus on the traditional electromagnetic wave without the shape of volute. As a hot spot of present research, vortex electromagnetic beam has a special equal phase scale and it contains orbital angular momentum, which can be used for information modulation to improve greatly the system capacity without expanding the system bandwidth. In the electromagnetic field and wave course, teaching of vortex electromagnetic wave can not only improve the breadth and depth of teaching contents, but also stimulate the students＇ thirst for knowledge and cultivate students＇ scientific thinking.
