Canlyniadau Dysgu

Wedi cwblhau'r modiwl dylai'r myfyrwyr fedru:

Demonstrate knowledge and understanding of EM waves generation, behaviour in free space and at dielectric boundaries.
Show critical understanding of EM guiding structures, both metallic and dielectric.

Disgrifiad cryno

This module develops an introduction to an EM theory and its applications in microwave devices. The full theory of transmission, reflection, dispersion and absorption of EM waves is developed for free-space, conductors and dielectrics. The module offers an in-depth knowledge of microwave circuits, transmission line theory, types of transmission lines and impedance matching of the RF networks. The theory underlying the generation of EM waves is presented, with discussions that consider the waveguides, Hertzian dipole and antennas.

Cynnwys

The module will cover topics in the EM theory and microwave devices in lectures and workshop sessions:
Electromagnetic Waves:
• Maxwell's equations, EM waves in free space, energy and Poynting vector, dispersion, absorption of plane waves in conductors, skin effect, reflection and transmission, dielectric and conducting boundaries.
Generation of electromagnetic waves:
Propagation between conducting plates, rectangular waveguides, cavities. Hertzian dipole, antennas.
Fundamentals of microwave devices:
Fundamental characteristics of microwaves and define common terms such as dB and dBm, Power loss, VSWR, Gain, Bandwidth, load, generator, transmission line, resistive loads, standing waves, waveguide components (Tees, attenuators, isolators).
Transmission line theory: Describe different types of transmission lines (Coaxial, planar transmission lines, waveguides etc.) and their properties, S-parameters and two port networks, Smith charts and impedance matching.
