Course Objectives:

The goal of this course is to introduce the working knowledge of electromagnetic wave theory and transmission lines with applications. Especially, the transmission of electromagnetic waves in free space is emphasized. The polarization of EM wave, which is crucial in communication systems, is introduced. This course starts with Faraday Law of Induction and it builts Maxwell’s equations with the introduction of displacement current. Circuit theory specifically adopted for transmission lines is also targeted. High power microwave transmission systems, waveguides and introduction to antenna theory are targeted as the applicatiıons of Maxwell’s equations.

Course Content:

Faraday Law of Induction, displacement current, wave equation, propagation in free space, wave polarization, wave propagation in lossy medium, energy carried by the wave, the interaction of EM wave with material boundaries (reflection and refraction), fiber optical systems, transmission line equations, transmission lines applications, introduction to antennas, Friis transmission formula and propagation, short dipoles
