'This is a truly unique book that covers a variety of computational methods for several important physical (electromagnetics) problems in a rigorous manner with a great depth. It will benefit not only computational mathematicians, but also physicists and electrical engineers interested in numerical analysis of electrostatic, electrodynamic, and electron transport problems. The breadth (both in terms of physics and numerical analysis) and depth are very impressive. I like, in particular, the way the book is organized: a physical problem is described clearly first and then followed by the presentation of relevant state-of-the-art computational methods.'
