The dispersion characteristics of the SPs are investigated using the dielectric constants values of the Ga As and the Alx Ga 1-x As media and the defined thickness, the Alx Ga 1-x As medium. The dispersion behaviours calculated results are listed for considered cases. It was shown that the frequency values against the wave vector values are affected in a strong manner by changing thickness, of the Alx Ga 1-x- As media and by changing the variation of the dielectric constants of Ga As against the Alx Ga 1-x As. The significance effects of the use of the left-handed (LH) medium as an upper layer of the proposed composition was demonstrated; the frequency values are remarkably increased using LH material as an upper layer. It was noticed that at certain conditions of the LH upper layer composition, similar results have been obtained such as found by using dielectric upper layer.
