内容简介
电磁场理论是现代电子技术的基础课程,其应用遍及整个国家经济,上至天文,下至地质,涵盖了工业、农业、军事、医学和环境保护等各个领域,即使饮食、家电等生活方面也得到广泛应用。没有电磁波的发射、传输和接收,就不会有电视、通信、雷达、遥感、测控和电子对抗等等。电磁理论也是许多交叉学科的孕育点,学习电磁场理论对培养学生严谨的科学作风、抽象思维能力及科学的创新精神起到非常重要的作用。深厚的电磁理论是欲在电子技术领域有所作为者不可少缺的功底。 电磁场理论的讲述无非是“从一般到特殊”和“从特殊到一般”两种途径,对不同读者两者各有其优点。根据作者二十余年讲授本课程的体会,在课程系统的总体安排上,按“从特殊到一般”的循序渐进方式,有利于初学者对本课程的理解;而讲授具体问题时,采用从“一般到特殊”的方法,则可以节省学时且理论上较为严谨。 本教材共分十章,章矢量分析作为学习电磁场理论的必要数学工具,强调了各种坐标系描述物理关系的一致性及三种主要坐标系的相互关系和场论基础。第二、三、四、六章为静电场、恒定电场、恒定磁场和电磁感应,涵盖了普物电磁学的全部内容,统一了普物电磁学和电磁场两种描述方法。第五章静态场的边值问题侧重于分离变量法和镜像法,以有限差分法为例说明数值法在解决复杂边值问题时的重要性。第七章时变电磁场总结了宏观电磁理论,引出麦克斯韦方程组,讨论能流密度概念为电磁波的论叙奠定基础。第八章较详细地论叙了平面电磁波的传播性质及其在边界面上的反射、折射,并对损耗媒质中的传播作了简要介绍。第九章导行电磁波讨论了导行波的基本原理和处理导行波的基本方法。第十章辐射讨论电磁能量的辐射原理,简介了基本辐射天线。
