Suslov %J Physics %D 2013 %I arXiv %R 10.1007/s10773-013-1764-3 %X We consider the radiation field operators in a cavity with varying dielectric medium in terms of solutions of Heisenberg's equations of motion for the most general one-dimensional quadratic Hamiltonian. Explicit solutions of these equations are obtained and applications to the radiation field quantization, including randomly varying media, are briefly discussed. %U http://arxiv.org/abs/1301.7328v2
