STUDENT COMPANION SITE Every new copy of Stuart Wentworth's Applied Electromagnetics comes with a registration code which allows access to the Student's Book Companion Site. On the BCS the student will find: 'ˆ— Detailed Solutions to Odd-Numbered Problems in the text 'ˆ— Detailed Solutions to all Drill Problems from the text 'ˆ— MATLAB code for all the MATLAB examples in the text 'ˆ— Additional MATLAB demonstrations with code. This includes a Transmission Lines simulator created by the author. 'ˆ— Weblinks to a vast array of resources for the engineering student. Go to www.wiley.com/college/wentworth to link to Applied Electromagnetics and the Student Companion Site. ABOUT THE PHOTO Passive RFID systems, consisting of readers and tags, are expected to replace bar codes as the primary means of identification, inventory and billing of everyday items. The tags typically consist of an RFID chip placed on a flexible film containing a planar antenna. The antenna captures radiation from the reader's signal to power the tag electronics, which then responds to the reader's query. The PENI Tag (Product Emitting Numbering Identification Tag) shown, developed by the University of Pittsburgh in a team led by Professor Marlin H. Mickle, integrates the antenna with the rest of the tag electronics. RFID systems involve many electomagnetics concepts, including antennas, radiation, transmission lines, and microwave circuit components. (Photo courtesy of Marlin H. Mickle.)

Stuart M. Wentworth received his B.S. degree in Chemical Engineering from Auburn University, Alabama, in 1982 and his M.S. (1987) and Ph.D. (19990) degrees in Electrical Engineering from the University of Texas at Austin. he has been a member of the Electrical & Computer Engineering faculty at Auburn University, Alabama since 1990. Dr. Wentworth's research has focused on the high frequency characterization of materials used for electronics packaging. He is the author of Fundamentals of Electromagnetics with Engineering Applications (Wiley). Dr. Wentworth has received numerous teaching awards at Auburn University, including the Birdsong Merit Teaching Award in 1999. He is a Senior member of the Institute of Electrical and Electronics Engineers (IEEE).
