The energy associated with an electromagnetic wave passing through a dielectric resides partly in the electromagnetic field and partly in the accompanying excitation of the dielectric. The theory of energy propagation through an absorbing classical dielectric having a single resonant frequency is presented in this paper. Simple expressions are derived for the velocity of energy transport associated with an electromagnetic wave, and for the finite energy relaxation time caused by the damping mechanism. The variations of these quantities, and of the absorption coefficient, with the relative values of the damping constant and dipole moment of the classical oscillator are investigated. This information is used to throw light on the basic mechanism of irreversible dissipation of energy by an electromagnetic wave in a dielectric. The similarities between the calculations of the dielectric constant by classical dispersion theory and by quantum mechanics are discussed.read more

Group velocity and nonlocal energy transport velocity in finite photonic structures
TL;DR: In this article, the authors derived an explicit relation between the group delay velocity vgd(ω), determined by the slope of the dispersion curves, and the nonlocal energy transport velocity vE(ω) in a lossless, finite, one-dimensional photonic crystal.

Slow light propagation in a linear-response three-level atomic vapor
TL;DR: In this article, the authors used a steady-state laser beam for optical pumping of the ground states prior to sending in the test pulse to control the amount of delay, which is in good agreement with a three-level linear dispersion calculation.

Evidence of birefringence and anomalous electromagnetic-pulse propagation in an organic light-emitting diode
TL;DR: In this paper, high-speed electromagnetic properties of organic light-emitting diode (OLED) are explored and it is shown that when a high-frequency (∼14 GHz) microwave pulse is injected into an OLED, the pulse is split into two peaks: one peak is delayed by 1.725 ns and another one is advanced by 0.183 ns, which suggests the existence of extremely low-speed group velocity.

Dynamical Theory of Crystal Lattices
Max Born,Kʿun Huang +1 more
TL;DR: Born and Huang's classic work on the dynamics of crystal lattices was published over thirty years ago, and it remains the definitive treatment of the subject as mentioned in this paper. But it is not the most complete work on crystal lattice dynamics.

Statistical-Mechanical Theory of Irreversible Processes : I. General Theory and Simple Applications to Magnetic and Conduction Problems
TL;DR: In this paper, a general type of fluctuation-dissipation theorem is discussed to show that the physical quantities such as complex susceptibility of magnetic or electric polarization and complex conductivity for electric conduction are rigorously expressed in terms of timefluctuation of dynamical variables associated with such irreversible processes.
