Abstract

In this paper we investigate the change of surface plasma (SP) resonance of a left-handed material (LHM) nano-slab. The intrinsic parameters of the LHM slab are suitable chose so that it has both negative permittivity and permeability in a frequency range of visible light. We calculate the attenuated total reflection (ATR) spectra of the LHM slab by use of the transfer matrix method. The spectra of different cases with various slab thickness and surrounding dielectrics of the LHM slab have been studied. The variations of SP resonance wavenumber and the corresponding resonance strength are discussed from the results of calculated ATR spectra.
