Electrodynamics of Solids: Optical Properties of Electrons by Martin Dressel

By Martin Dressel

During this ebook the authors completely talk about the optical homes of solids, with a spotlight on electron states and their reaction to electrodynamic fields. Their evaluate of the propagation of electromagnetic fields and their interplay with condensed subject is by way of a dialogue of the optical homes of metals, semiconductors, and superconductors. Theoretical innovations, dimension thoughts and experimental effects are lined in 3 interrelated sections. the amount is meant to be used by means of graduate scholars and researchers within the fields of condensed subject physics, fabrics technological know-how, and optical engineering.

23) the limiting case valid for free space with Jcond = 0 has already been derived in Eq. 22). Hence, the energy of the electromagnetic fields in a given volume either disperses in space or dissipates as Joule heat Jcond · E. 7). The real part of this expression, P = σ1 E 02 , describes the loss of energy per unit time and per unit volume, the absorbed power density; it is related to the absorption coefficient α c n by Jcond · E = 4π α E 02 . The phase angle between the current density J and the µ1 electric field strength E is related to the so-called loss tangent already introduced in Eq.

4d) give E 0i +E 0r −E 0t = 0 and (E 0i −E 0r ) cos ψi − ( 1 /µ1 )1/2 E 0t cos ψt = 0. 7a) . 4d) lead to (E 0i − E 0r ) cos ψi − E 0t cos ψt = 0 and (E 0i + E 0r ) − ( 1 /µ1 )1/2 E 0t = 0. 7c) . 7d) 1/2 1/2 These formulas are valid for Nˆ complex. To cover the general case of an interface between two media (the material parameters of the first medium are indicated by a prime: 1 = 1, µ1 = 1, σ1 = 0; and the second medium without: 1 = 1, µ1 = 1, σ1 = 0), the following replacements in Fresnel’s formulas are sufficient: Nˆ → Nˆ / Nˆ and µ1 → µ1 /µ1 .

22) which describes the intensity of the radiation S t = (c/16π)(E 0 H0∗ + E 0∗ H0 ). The attenuation of the wave is then calculated by 28 2 The interaction of radiation with matter the time averaged divergency of the energy flow ∇ ·S t = c n −2ωk 2 2ωk E 0 exp − r 4π 2µ1 c c , leading to 4π ∇ · S t ωk 2 =− =− α c n E 2t cµ1 µ1 . The power absorption, as well as being dependent on k, is also dependent on n because the electromagnetic wave travels in the medium at a reduced velocity c/n. e. 26) where v = c/n is the velocity of light within the medium of the index of refraction n.
