Conical diffraction and the dispersion surface of hyperbolic metamaterials
BALLANTINE, KYLE; EASTHAM, PAUL; DONEGAN, JOHN (2014)Hyperbolic metamaterials are materials in which at least one principal dielectric constant is negative. We describe the refractive index surface, and the resulting refraction effects, for a biaxial hyperbolic metamaterial, with ... -
Conical diffraction of a Gaussian beam with a two crystal cascade
LUNNEY, JAMES; DONEGAN, JOHN; BALLANTINE, KYLE; EASTHAM, PAUL; PHELAN, CIARAN (2012) -
Conical diffraction of linearly polarised light controls the angular position of a microscopic object
LUNNEY, JAMES; DONEGAN, JOHN; RAKOVICH, YURY; PHELAN, CIARAN; BALLANTINE, KYLE (2010)Conical diffraction of linearly polarised light in a biaxial crystal produces a beam with a crescent-shaped intensity profile. Rotation of the plane of polarisation produces the unique effect of spatially moving the ... -
Optical trapping using cascade conical refraction of light
DONEGAN, JOHN; BALLANTINE, KYLE; PHELAN, CIARAN; LUNNEY, JAMES (2012)
