A course is described in which the attempt is made to introduce first-year electrical engineering students to the basic principles upon which their chosen discipline is founded and to establish early the concept of a system. It is contended that an undergraduate course need not lag a decade behind current practice and current thinking but that, rather, the techniques taught and, indeed, the entire mode of approach can and should be completely up-to-date. 相似文献

A new introductory sequence in engineering electromagnetics is described. Its novel features include an axiomatic development of electromagnetic theory, the application of transform analysis to the solution of the important partial differential equations, and the use of engineering terminology in developing a distributed systems viewpoint. The sequence establishes a close relationship among electromagnetics, circuits, and system theory, and has been used successfully at the University of Iowa for the past three years. 相似文献

This paper proposes and demonstrates a polarization-analyzing CMOS sensor based on image sensor architecture. The sensor was designed targeting applications for chiral analysis in a microchemistry system. The sensor features a monolithically embedded polarizer. Embedded polarizers with different angles were implemented to realize a real-time absolute measurement of the incident polarization angle. Although the pixel-level performance was confirmed to be limited, estimation schemes based on the variation of the polarizer angle provided a promising performance for real-time polarization measurements. An estimation scheme using 180 pixels in a 1deg step provided an estimation accuracy of 0.04deg. Polarimetric measurements of chiral solutions were also successfully performed to demonstrate the applicability of the sensor to optical chiral analysis. 相似文献

A course in electrical engineering for freshmen, suitable for both engineering and non-engineering students, is presented. The course is intended to give the students an overall view of the field, at the same time teaching them enough fundamentals that they will be able to diagnose and develop simple circuits, getting a taste of design. A hydraulic analog is presented for ease and speed in teaching basic electrical concepts. An unconventional teaching technique, the "inclassdrill," is used, with encouraging results. 相似文献
