Research output: Contribution to journalArticlepeer-review

Abstract

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.
