Features for InstructorsThis new second edition provides greatly enhanced flexibility to the instructor faced with a one term electromagnetics course, as well as those with a second term, to continue using the same book. Optional new topics and extended discussion of core topics are provided in PDF files on the Student CD that match the text's 2-color format.A self-paced MATLAB tutorial on the Student CD lets you focus on instruction, not on teaching students how to use MATLAB. Resources for instructors include:· Complete solutions to all the MATLAB problems in Word or .m files.· PowerPoint slides of all figures in the text, by chapter.· Three sets of exams with solutions (first test, second test, final exam).· Animations in MATLAB, MPG files, and PowerPoint.The unique flexibility of this textbook allows it to meet a variety of course needs, instructor preferences, and even a second term's use. Instructors can suggest and help construct additional topics to be added to the publisher, which will be included in web downloads and then on updated versions for the new term.Features for Students· Ease your way into MATLAB with tutorials in the textbook and on the CD as well.· Wave propagation and transmission lines are emphasized in this text. Chapter 7 Transmission Lines has been further revised to be 100% independent of previous chapters so that the option of presenting the topic early in the term is easier than ever. · The MATLAB programs (.m-files) that are used to generate pictures in the book are now included on thebook-enclosed CD in order to encourage experimentation. · Animations of wave forms have been expanded to over 50 in number (new additions to be added continually) and a disk icon placed within the text to show where an Animation is pertinent.· Odd Answers to problems in the text (worked solutions to instructors only). Problems are now numbered according to the corresponding text section.
