Course description and aims
Electromagnetic waves (microwaves, millimeter waves, light waves) are used for applications such as signal transmission and sensing. These applications require controlling the propagation of electromagnetic waves depending on the purpose. Controlling the mode of electromagnetic waves that propagate through waveguides can realize the branching and coupling capabilities of electromagnetic power, as well as capabilities of frequency discrimination.
The instructor in this course will explain how the field distribution and propagation velocity of electromagnetic waves are determined when propagating in representative waveguides such as a coaxial line, metallic waveguide and dielectric waveguide. The instructor will also explain the scattering matrix used for characterizing electromagnetic wave circuits, then explain the operating principle and basic design methods of typical electromagnetic wave circuits for branching and coupling capabilities, frequency discrimination capability, and nonreciprocal functions that realize direction-dependent transmission of electromagnetic waves. Furthermore, the instructor will explain the concepts of the Radio Law.
Student learning outcomes
By the end of this course, students should be able to:
1) Understand the characteristics of electromagnetic waves propagating in waveguides.
2) Represent the characteristics of electromagnetic wave circuits.
3) Explain and design the operation principles of representative electromagnetic wave circuits.
Corresponding educational goals are:
(1) Specialist skills Fundamental specialist skills
(4) Applied skills (inquisitive thinking and/or problem-finding skills) Organization and analysis
(7) Skills acquiring a wide range of expertise, and expanding it into more advanced and other specialized areas
