Eligibility:
For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.
Course specific prerequisites
Basic knowledge of electromagnetic field theory, such as EEM015 Electromagnetic fields.
Aim
The aim of this course is to give a basic description and understanding of high frequency electromagnetic wave phenomena as they occur in modern applications as e g fibre optics, laser and microwave techniques and microelectronics. The students will learn to apply Maxwell's electromagnetic theory to solve electromagnetic problems which are closely connected to applications and research within this area and will get a broad theoretical understanding which they can later apply to specific applications (e.g. in photonics, microelectronics etc).
Learning outcomes (after completion of the course the student should be able to)
· describe different types of transmission lines and their characteristic parameters, understand wave propagation on transmission lines, and be able to use the Smith diagram to solve problems concerning transmission lines
· describe the electromagnetic fields in a waveguide and a cavity resonator, and use that to calculate power flow and attenuation
· understand the building blocks in optical fiber communication systems, together with system limitations coming from dispersion and attenuation
· describe different microwave devices (especially high frequency transistors), determine the length and termination of a waveguide from reflected wave measurements, measure twoport scattering parameters with a network analysator and design a microwave power amplifier.
· derive radiation from a given current distribution, be able to define and use basic antenna concepts, be able to understand and use the radar equation.
