ABSTRACT
In the present chapter, the optical properties of a three-axial
nanoellipsoid and their influence on the radiation of atoms and
molecules placed in the vicinity of such an ellipsoid are discussed.
This problem is very important since the three-axial ellipsoid
generalizes both a sphere and spheroids. On the other hand, even
quite spherical particles have, in fact, asymmetries, which have
a considerable influence on their optical properties because all
resonance degenerations are removed.
