Magnetic Absorption of Metal Nanoparticles

Abstract

The dependences of the magnetic absorption by spheroidal metal nanoparticles on the ratio between the particle curvature radii and the angle between the spheroid symmetry axis and the magnetic field vector of an incident electromagnetic wave are plotted and theoretically analyzed. An interesting result of the research is the growth of the energy absorbed by a spheroidal nanoparticle, as it becomes more oblate.
