Title: MICROWAVES

 

Credits: 3

UW Course Catalog Description
:

Microwave transmission, transmission lines and waveguides. Microwave circuits. Scattering parameters. Microwave resonators. Microwave using ferrites. Generation and amplification of microwaves. Klystrons, magnetrons, traveling wave tubes. Semiconductors in microwaves.

Coordinator:
Avni Morgül, Professor, Electrical Engineering



Goals: This course provides seniors majoring in the electronics and/or communications, and graduate students a background in microwave theory and applications. Students learn the operation principles, analysis and design of basic passive and active microwave devices.

 

Learning Objectives:

 

At the end of this course, students will be able to:

1.    Apply EM wave equations to microwave systems and components.
2.    Design waveguide and microstrip transmission lines with given characteristics.
3.    Analyze and design passive MW components such as directional couplers, power divider/combiner or filter with given characteristics.
4.    Understand operation principles, of basic passive and active microwave devices.
5.    Conduct a microwave measurement experiment such as MW impedance or SWR measurement.

Course Structure: After a short review of EM theory this course gives the analysis and design methods of transmission lines (waveguides and microstrips) and other passive MW circuits. The second part of the course the operation principles and applications of the active, low power semiconductor and high power microwave devices. There will be 3-6 homeworks depending on the studied subjects for the firs half of the course. During the second half, the lectures are supported by laboratory experiments and a term project.

The grading = Homework = 10%, Lab. = 10%, Midterms= 40%, Final =40% (subject to minor changes)

Computer Resources: EE department PC Labs.

Laboratory Resources: Microstrip and Waveguide microwave experiment kits and standard measuring instruments in the Telecommunications Lab.

Outcome Coverage:
 

a) An ability to apply knowledge of mathematics, science and engineering. Students should understand partial differential equations and their solutions in time domain and phasor space. They use basic electromagnetic theory and Maxwell’s equations. They also need to use complex algebra. In addition, a basic knowledge of solid-state physics is also required.
b) An ability to design and conduct experiments, as well as to analyze and interpret data. During the lab. sections, students learn how to set up a given circuit, how to measure the different electrical quantities and how to interpret the outcomes. Students are divided into two groups and perform 6 experiments and prepare 3 reports. The interpretation of the results should be given in the reports.
c) An ability to design a system, component, or process to meet desired needs. Throughout the homeworks and other exams they practice how to analyze and design passive microwave components and microwave systems to satisfy certain specs.
d) An ability to function on multi-disciplinary teams. The lab. experiments are performed by groups. They learn how to share roles during the experiments, such as assembler, reader of instruments and reporter.
e) An ability to identify, formulate and solve engineering problems. The midterm and final exams of this course has open-book and closed book sections. So the student should have the ability to identify the required equations and method to be used for solving a problem, instead of memorizing the equations.
g) An ability to communicate effectively. Each student should prepare three lab reports and one term project. So they learn how to prepare official reports.
j) A knowledge of contemporary issues. Students choose a project subject in microwaves which is not studied in the lectures, by serching papers in the recent periodicals. So they get an idea about the contemporay subjects in microwaves, and study one of these subjects.
k) An ability to use the techniques, skills and modern engineering tools necessary for engineering practice. The students use computers for report and project writing. They use modern laboratory equipment during microwave measurement experiments.
