Photon–The Minimum Dose of Electromagnetic Radiation
SPIE Proceedings, 2005–34 [kgm 2 /s]. A point emitter like an atom can be regarded as a dipole in the fourth dimension. The length of such dipole is measured in the direction of the line element cdt, which in one oscillation cycle means the length of one wavelength. For a dipole in the fourth dimension, three space directions are in the normal plane which eliminates the ...

Electromagnetic Field and Photons
1984The probabilistic treatment of the electromagnetic field in vacuum would have to be based on the results of Chapter 7 dealing with random fields. But the definition of a random field there proceeds, as should be the case in probabilistics, from the notion of a continuous concrete object regarded as the carrier of a field.

Manipulating electromagnetic radiation with magnetic photonic crystals
Optics Letters, 2007We examine manipulating electromagnetic waves in magnetic photonic crystals (MPCs) with external magnetic fields. We predict new giant magnetoreflectivity and giant magnetorefractivity effects: with an external magnetic field of a magnitude much smaller than the anisotropy field of the ferromagnet, the MPC can be changed from completely reflecting to ...

Electromagnetic Bloch waves at the surface of a photonic crystal
Physical Review B, 1991We find that electromagnetic modes are localized at the interface between air and a photonic crystal. General arguments that surface modes must always exist for some termination of any surface of a photonic crystal are presented, and the importance of the surface band structure for semiconducting laser systems is discussed.

Quantization of the Electromagnetic Field: the Photon
2017Understanding the classical field theory of coupled dynamical scalar fields and vector potentials is rather difficult, with the quantized theory even more so, due to the fact that the Hamiltonian is no longer quadratic in the field variables and the field equations are nonlinear.

Photon-drag experiment and the electromagnetic momentum in matter
Physical Review B, 1986The photon-drag experiment of Gibson et al. [Proc. R. Soc. London, Ser. A 370, 303 (1980)], operating in the millimeter region, is analyzed and compared with predictions following from the electromagnetic energy-momentum tensors of Minkowski, of Abraham, of Peierls, and of Einstein and Laub.
