Research interests

  • Full-Wave Electromagnetic Modelling of the Production of Optical Forces and Torques in Laser Trapping

    Optical forces and torques acting on a microparticle in a laser trap arise from the transfer of momentum and angular momentum from the trapping beam to the particle, and can be found by calculating the scattering of the trapping beam by the particle. Since laser-trapped particles are of sizes comparable to the trapping wavelength, a full electromagnetic wave solution is required.

  • Optical Measurement of Microscopic Forces and Torques

    An alternative to the calculation of the scattering by a laser-trapped particle is to measure the scattered light, and from this, determine the optical force and torque acting on, and the position within the trap, of the particle.

  • Extremely Asymmetrical Scattering in Bragg Gratings

    Extremely asymmetrical scattering is being investigated theoretically and computationally in collaboration with the Physical Optics Program, School of Physical and Chemical Sciences, Queensland University of Technology.

  • Micro-Opto-Mechanical Systems (MOMS)

    Theoretical development of MOMS and MOMS-related techniques.
