内容简介
本书在开始先给出电磁学中的量纲、单位制及矢量分析的基础知识，然后作为主体全面叙述电磁学即电磁场与电磁波的经典理论。包括恒定电磁场，集总参数电路元件中的电磁场，传输线的分布参数电路理论和场理论，平面波的传播、衰减、偏振、反射、折射和衍射，天线和电磁辐射，荷电粒子、载流子及载流导体在电磁场中的运动，介电材料和磁性材料，波导和谐振器等。在此基础上进一步介绍了电磁学的进展和应用，如直线电机，雷达，卫星通信，卫星定位，无线移动通信，光纤光学，生物电磁学，高速数字电路中的电磁效应等的基本概念。给出求解电磁场问题的数值方法。 本书不着重追求艰深的理论演绎，不陷入繁琐的、普遍性的数学推导，而是帮助读者学到完整的、具体的和生动的电磁学知识，是一部与国内目前流行的教科书的风格很不相同的教材，很值得一读。
