摘要
电子信息工程的专业课程《电子线路》诠释了低、高频波段的信号放大与变换,而专业课程《电磁场》则诠释了射频波段的信号传输、辐射,两门课程的教学内容构成了全波段信号处理的理论基础。为提高专业师生针对《电磁场》这门课程特征问题的理解,在引入Maxwell电磁场方程组的基础上,通过分析静电磁、动电磁与变辐射及导出相应的公式,凝炼并总结了电磁场在射频波段的应用和发展。
Electronic Circuit,one professional course of Electronic Information Engineering,interprets signal amplification and transformation in low and high frequency band,while Electromagnetic Field,another professional course of Electronic Information Engineering,interprets signal transmission and radiation in radio frequency band.The teaching contents of these two courses constitute the theoretical basis for signal processing in full band.Based on the introduction of Maxwell electromagnetic field equations,by analyzing static electromagnetic field,dynamic electromagnetic field and variable radiation as well as deriving formulas,the researcher refined and summarized the application of electromagnetic field in radio frequency band and its development.
