Adecadeago,whenthe taskof developing thisbookwasinitiated, therewerefew available
texts on computational techniques for electromagnetics. Although a large number have
appeared since then, none attempt to treat both integral and differential equation formulations in a unified manner. The presenttext is intended to fill that gap and is designed for
graduate-level classroom use or self-study. Its primaryfocusis open-region formulations,
andwhileresonant cavity andantennaapplications aretouchedon in places, themajority of
the material is presented in thecontextof electromagnetic scattering. We have attempted to
provide enoughdetailto enablea readerto implement theconcepts in software. In addition
to a few subroutines in Appendix C, a collection of relatedcomputerprograms is available
through the Internet. Earlierdraftsof the material weretestedin graduate courses taughtat
the University of Illinois and the Georgia Institute of Technology as wellas in a numberof
continuing education courses. The authors sincerely appreciate the comments of former
students, colleagues, and the dozen or more reviewers who offered critiques during the
book's development.
