Strongly anisotropic particles with hyperbolic dispersion that are small compared with the wavelength show strong resonance in the near infrared. The unique resonance modes are insensitive to the host refractive index and independent of particle size. In addition, the far-field direction of scattering does not depend on incident angle. Because the strength of resonance is comparable to a plasmonic nanoparticle in the visible region, a hyperbolic-dispersed particle is a promising scatterer as well as local heater in the near infrared.
