General description
This course will enable students understanding time-varying electromagnetic fields and electromagnetic waves, and wave propagation phenomena, which are of essential importance in modern communications. The course focuses on the fundamental concepts of electromagnetic theory that are presented by the general form of time-varying Maxwell’s equations, physical significance of these equations, how fields are related, and how are they related to the medium properties. Students will be able to apply boundary conditions for fields at the interface of two different media, to use wave equation to find solutions to Maxwell’s equations, and especially, to study plane wave properties and characteristics as a solution, and medium properties of different types: dielectric (lossless and lossy), conductor and perfect conductor. Students will be able to understanding wave propagation mechanisms at interfaces, Poynting theorem and power and energy considerations, and the concept of stored energy and radiated power.
This course will also provide students with the basic theory of transmission lines, and focuses on the basic properties of the most commonly used transmission lines and waveguides and their relative advantages in a broader context. Students will be able to understanding the key differences between circuit theory and transmission line theory.
