Calculating coherent light-wave propagation in large heterogeneous media
Tom Vettenburg, Simon A. R. Horsley, J. Bertolotti
Understanding the interaction of light with a highly scattering material is essential for optical microscopy of optically thick and heterogeneous biological tissues. Ensemble-avera…
Nanoscale design of the local density of optical states
Sandro Mignuzzi, Stefano Vezzoli, Simon A. R. Horsley +3
We propose a design concept for tailoring the local density of optical states (LDOS) in dielectric nanostructures, based on the phase distribution of the scattered optical fields i…
A Luneburg lens for spin waves
N. J. Whitehead, S. A. R. Horsley, T. G. Philbin +1
We report on the theory of a Luneburg lens for forward-volume magnetostatic spin waves, and verify its operation via micromagnetic modelling. The lens converts a plane wave to a po…
Scattering of accelerated wave packets
S. Longhi, S. A. R. Horsley, G. Della Valle
Wave-packet scattering from a stationary potential is significantly modified when the wave-packet is subject to an external time-dependent force during the interaction. In the semi…
Topology and the optical Dirac equation
S. A. R. Horsley
Through understanding Maxwell's equations as an effective Dirac equation (the `optical Dirac equation'), we re--examine the relationship between electromagnetic interface states an…
Designing scattering-free isotropic index profiles using phase-amplitude equations
Chris King, Simon Horsley, Thomas Philbin
The Helmholtz equation can be written as coupled equations for the amplitude and phase. By considering spatial phase distributions corresponding to reflectionless wave propagation…
