The electromagnetic analysis of plasmon-resonance-based all-optical magnetic recording is performed. This analysis is based on the treatment of plasmon resonances as an eigenvalue problem for specific boundary integral equations. The plasmon modes which can be excited in circular nanoholes and cylindrical nanoshells by circularly polarized light are theoretically and numerically studied. Dramatic enhancement of circularly polarized light intensity on the nanoscale through the excitation of specific plasmon modes in uniaxial nanostructures is demonstrated.
