Scattering by plasmon polaritons on a metal surface with a detuned roughness spectrum.
The effects of plasmon polariton excitation on a metal surface with weak one-dimensional roughness are studied experimentally. It is shown that backscattering enhancement requires the excitation of counterpropagating polaritons, whereas surface waves traveling in one direction produce diffuse scatter without a strong backscattering peak.
