Surface plasmon—polaritons on ultrathin metal films

Abstract: We discuss the surface plasmon-polaritons used for ultrathin metal films with the aid of linear response theory and make comparisons with the known result given by Economou E N. In this paper we consider transverse electromagnetic fields and assume that the electromagnetic field in the linear response formula is the induced field due to the current of the electrons. It satisfies the Maxwell equation and thus we replace the current (charge) term in the Maxwell equation with the linear response expectation value… Show more

“…On the other hand, the surface plasmon-polaritons (SPPs) in metals can be excited, which can localize light and alter the field distribution at subwavelength scale. [5][6][7][8] SPP resonances could play a key role in enhancing the MO response. Therefore, combing SPPs with MO is of particular interest, as it can lead to the observation of new optical phenomena such as enhanced optical transmission, sub-wavelength confinement of optical fields, and subwavelength optical resolution.…”
