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.
