简介

《电磁场与电磁波(英文版》内容简介:This is a university-level textbook on electromagnetic fields and waves for undergraduate programs in electronic and information engineering, focusing on the basic properties of electromagnetic fields and waves, with emphasis on time-varying fields. With the rapid development of information technology, a thorough understanding of and familiarity with the properties of electromagnetic fields and waves, along with the relevant analytical tools and practical applications are expected for professionals working in the field of information technology. A course on electromagnetics is therefore an important part of the curriculum that forms the essential knowledge base for undergraduates majoring in information technology and electronic engineering.
