Wave propagators for transient waves in periodic media

Summary, in English

One-dimensional propagation of transient EM-waves in periodic media is studied.

The media are periodic in the direction of propagation and can be of finite

or infinite length. Wave propagators, that map a transient field from one point

in the medium to another, are introduced. A number of useful relations for

the propagators are presented. Some of these relations are used in the determination

of explicit expressions for the short time behavior of a transient

wave as it propagates in a periodic medium. The theory is exemplified by

several numerical examples.
