| Module Aims |
To develop an understanding of wave engineering principles with illustrations from microwave signal transmission, processing, and electronics.
|
|
|
| Learning Outcomes |
The main outcome is to develop an understanding of the principles and a familiarity with the jargon and terminology that will allow you to grasp the technological issues illustrated in the second half of the course. Since the concepts are generally accepted to be difficult for most students, particularly those who do not have a strong maths or physics background, the content has been deliberately restricted from that available in the recommended texts. |

Lecturer - Dr C Free
This half of the course introduces the student to a wide range of applications; existing and proposed; also to the technology behind active devices which are used for these applications.
[1-2] Propagation in materials, conductors and dielectrics.
[3-4] Applications; microwave ovens, sub-surface radar, radiometry.
[5-6] Vacuum tube technologies. TWTs and Klystrons.
[7-8] Discrete active semiconductor devices. Diodes, FETs, HBTs.
[9] Substrate material technologies for microwave semiconductor devices.
[10-12] Microwave IC technologies. HMICs, MMICs, Applications and limitations.
[13-15] Problem classes 1-3 (three lectures wort |

| Selected Texts/Journals |
Students will be expected to have read around the subject and to have a firm grasp of a range of factual material.
Essential for both parts of the course:
Collin, R. E. Foundations for Microwave Engineering, 2nd ed. 1992 0-07-112569-8 McGraw-Hill International Ed. £22.99 A
This is a classic reference book. If you only buy one book, buy this one. It has chapters on EM theory, transmission lines and waveguides, waveguide circuit theory, matching and impedance transformation, passive devices, resonators, periodic structures and filters, tubes, solid state amplifiers, parametric amplifiers, and oscillators and mixers. 924 pages. Good value for money.
Recommended
Liao, S. Y. Microwave devices & circuits. 3rd ed. H/B 0-13-583204-7 Prentice Hall £26.95 B
This book is a reasonable overview of the subject, largely descriptive in tone but with some nice mathematical development here and there. It has good sections on stub tuner matching. It covers a large variety of active devices, semiconductors and vacuum tubes, and has a section on ferrites.
Kraus, J. D. Electromagnetics. 4th ed. 0-07-112666-x McGraw-Hill 1991 £21.95 B
This is a classic text. It covers the standard transmission line and microwave topics and also has a chapter on antennas at an introductory level. (There is a specialised book by the same author, "Antennas" edition 2 1988) It comes with an instructor's solution manual which may be purchased as a guide to the excellent problems. For my taste, it is rather short on physical explanation, but the potted descriptions benefit by being short and easy to learn if you want to adopt this approach to the subject. Its section on s-parameters is weak. |
