 In this paper we apply the coupled dipole method to study the magneto-optical response of silver nanoparticles. We study the linear dichroism of spheroidal nanoparticles in the presence of small static magnetic field. The dichroism of single nanoparticle is calculated analytically. We show that single and dimer of spheroidal nanoparticles exhibit linear dichroism which depends on the direction of incident light with respect to direction major axis of spheroid and the static magnetic field.

Keywords: spheroid, dipole approximation, dichroism, absorption cross section.
