Abstract :
The scattering of TE polarized plane wave by electrically small metal-coated dielectric cylinders is investigated with a particular emphasis on the enhancement of the near fields. If the wavelength of illumination is properly chosen, two unique near field distributions can be formed along the cylinders. It is shown that the enhanced near fields are localized around two interfaces of the coating metal layer and closely related to the surface plasmon resonances.
