    Abstract
    We report possibility of surface plasmon polariton modes that can be excited by incident light of a fixed frequency coming at wide angles. We experimentally show such modes in structures with smooth dielectric-metal-dielectric interfaces having 2-D dielectric patterns on top. Calculated field profile establishes the field localization at the metal-dielectric interfaces. We show that the position and dispersion of the excited modes can be controlled by the excitation geometry and the 2-D pattern.We report possibility of surface plasmon polariton modes that can be excited by incident light of a fixed frequency coming at wide angles.
