Topic outline

  • ETE 415 : Microwave Engineering

     The course will introduce three basic tools of a microwave engineer viz. smith chart, s-parameter and signal flow graph. The lectures would try to emphasize the need to understand the key concepts behind these tools for solving various analysis and design problems in microwave engineering. The concepts of microwave measurement both in the traditional microwave bench and network analyzer would be explained and some typical applications of the tools like impedance matching, network analyzer calibration, and directional coupler characterization would be demonstrated. The course would lay the foundation for further exploring the vast area of microwave engineering analysis and design.

      Welcome to Microwave Engineering Course.

      This course consists of 10 Modules. You should spend about 5 - 7 hours a week on watching video lectures and completing problems and quizzes. The expectation is for you to keep pace with the course and use the discussion forums to ask questions, answer each other's questions and share applications that you have seen from your work or your hobbies .

      • Please review the course profile. This will explain the logistics of the course, such as how grading will be done and provide a module by module course outline of what will be covered in this course.
      • Then locate each modules' material thoroughly.
