Anharmonic Alternating Electromagnetic Fields in Dispersive Materials

  • A. B. Shvartsburg


This chapter is devoted to the dynamics of nonsinusoidal electromagnetic fields in dispersive and conducting media. These media are characterized by some internal time scales that depend upon the media parameters such as cutoff frequencies or conductivities. If these parameters vary over time, their temporal variations provide the evolution of the structure of the EM field interacting with such non-stationary systems. Thus, the traditional sinusoidal waves are known to vary their frequencies and amplitudes while traveling through media with time-dependent absorption (e.g., cross-modulation phenomena) or reflecting from moving boundaries (Doppler effect). A vast array of literature regarding these problems has been published but will not be considered here.
