Query: Green's functions theory of nanophotonic cavities with hyperbolic
  materials   We develop a theory of the quasi-static electrodynamic Green's function of
deep subwavelength optical cavities containing an hyperbolic medium. We apply
our theory to one-dimensional cavities realized using an hexagonal boron
nitride and a patterned metallic substrate.
