Fano resonance based on long range surface phonon resonance in the mid-infrared region

Surface plasmon polaritons with noble metals lack the capability to restrain an optical field in the long wavelength region, while surface phonon polaritons with polar di-electric crystals have been regarded as a potential low-loss alternative. In this paper, long range surface phonon resonance (LRS...
