interesting and important applications. While adapted from his popular and more extensive work, Field and Wave Electromagnetics, this text incorporates a number of innovative pedagogical features. Each chapter begins with an overview which serves to offer qualitative guidance to the subject matter and motivate the student. Review questions and worked examples throughout each chapter reinforce the student's understanding of the material. Remarks boxes following the review questions and margin notes throughout the book serve as additional pedagogical aids. 606 $aElectrical engineering$vTextbooks 606 $aElectromagnetism$vTextbooks 615 0$aElectrical engineering 615 0$aElectromagnetism 676 $a537 700 $aCheng$b David K$g(David Keun),$f1918-2012,$0863666 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910153061303321 996 $aFundamentals of engineering electromagnetics$93408037 997 $aUNINA
