Course Structure:
Lectures are organized so that students can analyze and design microwave circuits assigned in each lab project. The first few weeks cover basic electromagnetic theory in transmission lines and waveguides. Different techniques such as ABCD- and S-parameter approaches are presented to analyze the microwave circuits. Each lab project is designed so that the students are able to apply the theory studied in class to practical problems.
Laboratory projects:
Lab 1 Time- and frequency-domain analysis of a TL model
Implementation of inverse chirp-Z transform
Lab 2 Dielectric constant estimation using transmission method
Forward and inverse problem in EM

Grading: 25% midterm exam, 25% final exam, 30% lab projects, and 25% homework assignments
Note: Different grading policies will be used for undergraduate and graduate students.
Requirement for EE462 students
(1) Final project will be based on experimental work and simulations using Ansoft (or similar products). Detailed analysis including Matlab simulations will not be required.
Requirement for EE572 students
(1) Final project must contain experimental work, simulations using Ansoft (or similar products), and detailed analysis including Matlab simulations.
(2) An extra assignment will be included in the final exam.
Outcome Coverage:
(a) An ability to apply knowledge of mathematics, science, and engineering. The majority of the lectures, homework and projects deal with the application of electromagnetic theory. Mathematical formulations are commonplace throughout the course. (H)
(b) An ability to design and conduct experiments, as well as to analyze and interpret data. This course uses microwave equipment which must be calibrated carefully to obtain good results. (H)
(c) An ability to design a system, component or process to meet desired needs within realistic constraints such as economic, environmental, social, political, ethical, health and safety, manufacturability and sustainability. The course materials are organized so that students will be able to analyze and test microwave materials. Each project will start with a detailed analysis. The final project will involve a design of a simulation tool. (M)
(d) An ability to function on multidisciplinary teams. N/A
(e) An ability to identify, formulate and solve engineering problems. The lab projects are designed so that students are required to solve problems using microwave CAD and measurement systems. (M)
(f) An understanding of professional and ethical responsibilities. N/A
(g) An ability to communicate effectively. Students must prepare extensive written project reports. Grades are given for writing quality as well as technical content of the reports. (M)
(h) The broad education necessary to understand the impact of engineering solutions in a global, economic, environmental and societal context. Microwave engineering is important for understanding the functions of wireless devices. Students will be able identify the problems associated with high-frequency devices. (L)
(i) A recognition of the need for, and an ability to engage in life-long learning.The course emphasizes the rapid change in technologies employed in the microwave industry and a need for the professional to maintain a state-of-the-art knowledge. (L)
(j) Knowledge of contemporary issues. Contemporary issues discussed include the problems with the current high-frequency devices. (L)
(k) An ability to use the techniques, skills and modern engineering tools necessary for engineering practice. Students use microwave CAD software (Ansoft HFSS) and modern microwave measurement systems (network analyzer). (M)
