## Description

- description: 'Surface plasma waves (SPWs) are usually discussed in the context of
    a metal in contact with a dielectric. However, they can also exist between two
    metals. In this work we study these bimetallic waves. We find that their dispersion
    curve always cuts the light line, which allows direct optical coupling without
    surface grating structures. We propose practical schemes to excite them and the
    excitation efficiency is estimated. We also show that these waves can be much
    less lossy than conventional SPWs and their losses can be systematically controlled,
    a highly desirable attribute in applications. Conducting metal oxides seem fit
    for experimental studies. '
