An apparatus comprises a slider configured for heat-assisted magnetic recording. A near-field transducer comprising a peg is situated at or near an air bearing surface of the slider, and an optical waveguide of the slider is configured to couple light from a light source to the near-field transducer. The peg comprises a hyperbolic metamaterial, and the near-field transducer may further include an enlarged portion from which the peg extends, where the enlarged portion may also comprise a hyperbolic metamaterial.
