The localized surface waves at the interface between a semi-infinite periodic multilayer structure containing alternate å-negative (ENG) and the ì-negative (MNG) layers and a uniform right-handed material and also a uniform left-handed metamaterial have been investigated. We demonstrated that in the presence of uniform right-handed materials, this system can support TE and TM-polarized surface waves depending on the relative thicknesses of the ENG and the MNG layers. But, in the presence of

These localized modes can have two different transverse structure related to the order of the ENG and the MNG layers; one with a hump at the interface between uniform material and the cap layer and the other one with a hump at the interface between the cap layer and the periodic multilayer structure. 
