電磁學(英文班)

Electromagnetic theory is the study of electric and magnetic fields and signals in space and time. It is essential to various applications in electrical engineering. This course will present a unified approach to electromagnetic theory based on postulates. The concept of fields (spatial distribution of physical quantities) and important mathematic tools are emphasized. Electrostatic and magnetostatic fields in space are then discussed. Time-varying fields, Maxwell’s equations, and concepts of electromagnetic waves will be introduced at the end of the semester. This course will be divided into two modules and taught by two teachers respectively. All classes will have the same materials, schedules, and grading policy. Computer software (Matlab) will be utilized in the course to enhance the learning process.

physics, calculus, differential equation, circuit theory
