Query: Hyperbolicity in 2D transition metal ditellurides induced by electronic
  bands nesting   Naturally occurring hyperbolic plasmonic media is rare, and was only recently
observed in the 1T$'$ phase of WTe$_2$. We elucidate on the physical origin of
this strong infrared hyperbolic response, and attribute it to band-nested
anisotropic interband transitions. Such phenomenon does not occur in general
anisotropic materials, at least not in their pristine state. However,
band-nested anisotropic interband transitions can in principle be induced via
proper electronic band nesting. We illustrate this principle and demonstrate a
topological elliptic-to-hyperbolic transition in MoTe$_2$ via strain
engineering, which is otherwise non-hyperbolic.
