Nonlinear wave propagation in the complex cavity with anisotropic hyperbolic metamaterial based on gold nanowires tilted relatively to outer boundary are investigated. We have estimated the effect of increasing of density of photonic states of electromagnetic field in the cavity, besides hyperbolic medium, by direct calculation of modal field and dispersion equation. The transfer matrix method was adopted for arbitrary orientation of optical axis according to slab boundary using 4x4 Berreman matrix. The eigenstates calculation supported Poynting flux control in each area of the cavity. Super-Planckian thermal emission in far zone is present.
