Review of fluctuational electrodynamics and its applications to radiative momentum, energy and entropy transport

摘要: Quantum and thermal fluctuations of electromagnetic fields, which give rise to Planck's law blackbody radiation, are also responsible for van der Waals Casimir forces, as well near-field radiative energy transfer between objects. Electromagnetic waves transport energy, momentum, entropy. For classical the dependence above mentioned quantities on temperature is well-known mainly due work. When effects, namely collective influence diffraction, interference, tunneling waves, become important, theory no longer valid. Of entropy transfer, role effects momentum two half-spaces separated by a vacuum gap (van pressure in gap) was first determined Lifshitz, using Rytov's fluctuational electrodynamics 1956. Subsequently, Dzyaloshinskii, Pitaevskii, employing sophisticated methods from quantum field theory, generalized Lifshitz' result layer case dissipative half-spaces. The appreciated only late 1960s and, subsequently, last decades because enhancement surface waves. played has not been investigated so far, at least when distribution non-uniform.
