Multiforms, Dyadics, and Electromagnetic Media
Wiley-IEEE Press (Verlag)
978-1-118-98933-3 (ISBN)
This book applies the four-dimensional formalism with an extended toolbox of operation rules, allowing readers to define more general classes of electromagnetic media and to analyze EM waves that can exist in them
End-of-chapter exercises
Formalism allows readers to find novel classes of media
Covers various properties of electromagnetic media in terms of which they can be set in different classes
