Abstract: The new analytical theory is developed describing propagation of plasmon polariton localized at the interface between a dielectric uniaxial crystal and an isotropic metal. The theory relates to the crystal cut choice corresponding to the sagittal plane parallel to the optical axis. For this geometry the compact dispersion equation is derived admitting exact explicit solutions for all physical parameters of the plasmon polariton for an arbitrary slope of the optical axis to the interface plane. Results are illustrated for a series of uniaxial crystals with gold coatings.
