Microwave engineering education using web-based instruction
chapter one
background to study
The electronic information transfer revolutionizes the flow of information in a similar manner as the print material did over 400 years ago. The opportunity for mass production of the written knowledge has transformed the classical methods of teachings. Electronic publishing, with its free flow of knowledge, has already reshaped the structure of our libraries, and it is posed to influence not only the physical structure of the classroom but also the style and methods of teaching. Even the technical publications distributed by the Institute of Electrical and Electronics Engineers (IEEE) as journals or symposia digests are gradually moving to the electronic format. It is not too far off mark that, in a short time, the technical papers are going to merely be a movie clip of the actual experiments or numerical models of the reported paper. The IEEE Microwave engineering Theory and Techniques (MTT) Society has led this campaign and is poised to provide the information-age benefits to its members. Since one of the primary responsibilities of any professional society is the continuing education of its members, it is natural to expect the MTT Society to initiate educational initiatives. As a result of advances in telecommunication and the popularity of the Internet, electronic multimedia now could augment the traditional teaching methods. Hence, the Education Committee initiated the Microwave Multimedia Module (M4) project, in addition to many other efforts. The Drexel University team of Mohammed-Reza Tofighi, a Ph.D. student, and myself has responded to the M4 project challenge. Our goal is to develop an E-book that covers various topics in passive and active microwave circuits in the hope of assisting MTT Society members in their continuing education efforts. This product is developed as standard “post page” and will be completed in mid-2001. The copyrighted material will then be delivered to IEEE as an electronic book.

Approach
The approach of providing Web-based education relies on providing computer-aided-design (CAD) solutions to the practical problems. This approach follows the traditional teaching methods inherited from classical masters and modified in the last 50 years by many scholars. The primary value of multimedia-based educational material, such as E-books, is the opportunity to use graphical approach to integrate sophisticated CAD simulations in the delivery of complex engineering concepts.
For example, the wave propagation concepts that were left to the imagination as a result of the static characteristic of the paper book now can be addressed using electronic modules, such as a movie player. Performance comparison of different solutions to the same problem could also be made by liberal use of attractive colors, which remains a major cost deterrent for publication of standard textbooks.

The specific goals of the Drexel University’s M4 project are to: • Subdivide the topics covered in many reference text books in terms of fundamental, practical, and the state-of-the-art topics • Provide microwave engineering circuit problems and their solutions based on a number of practical examples to emphasize theory of operation, design techniques, realization, simulated performance, optimization and design limitations • Port the electronic data files from CAD packages to HTML files and use both the Web and CD-ROM as electronic books. Subject Matter The subject matter covered in this electronic textbook is: • Transmission line and discontinuities • Impedance matching techniques • Multiport network parameters • Junctions and directional couplers
