ABSTRACT
Nanoparticles in the shape of oblate or prolate spheroids, which
are obtained as a result of the ellipse rotation about the short
axis or the long axis, correspondingly (Fig. 7.1), have an even
greater significance for optical applications than spherical particles
have. On the one hand, understanding of the optical properties of
spheroid-shaped nanoparticles allows estimating of the influence
of small deviations from sphericity on various applications. On the
other hand, great attention is paid to spheroidal nanoparticles that
differ essentially from spherical particles (nanoneedles, nanorods,
nanodiscs) since the plasmon resonances in particles of this kind are
rich in structure, which allows their usage in many applications.
