Nonlinear electromagnetics [book review]

The theory of nonlinear electric circuits is a highly advanced subject. It has been intensively developed in the Soviet Union under the direction of N. M. Kryloff and N. N. Bogoljubov for the past fifty years and has been an active topic of research in western countries for about thirty-five. On the other hand, research on nonlinear electromagnetic waves is just getting under way and has only recently started to receive the serious attention it deserves. Of course, much of this attention is due to the expectation that nonlinear electromagnetic wave phenomena will find use in radically new devices and radically new systems.
