The present knowledge of anisotropic electrodynamics rests on the power of appropriate approximation methods. An exact treatment of these systems faces essentially two problems:
(1) the evaluation of a closed space-time representation of the Green-function, (2) the difftculty in taking full account of the directional dependence of the electrodynamic quantities. This paper gives the exact treatment of two simple systems: isotropic, but uniformly moving, matter and the uniaxial crystal,. Space-time representations for the complete Green-tensor and radiation expressions valid for arbitrary sources are derived in both cases. The general formulae permit the straightforward computation of Cerenkov-spectra. Moreover, the theory is capable of calculating a radiation process like synergic synchrotron-Cerenkov-radiation.
In the uniaxial crystal case this includes a good approximation to the emission of a relativistic Larmor-electron into a magnetized plasma. 372
