The textbook we offer to the reader is based on a two-term course of lec tures, "Electromagnetic Response of Material Media," that the authors gave for a number of years to the final-year students of the Physics Depart ment of Moscow University. This course built on courses in quantum electronics, nonlinear optics and theoretical fundamentals of quantum radiophysics; students are as sumed to have mastered the fundamentals of quantum mechanics, laser physics and nonlinear optics. The essential core of the course, and hence of the book, is the current general theory of electromagnetic response...
