Graded index lenses for spin wave steering
N. J. Whitehead, S. A. R. Horsley, T. G. Philbin +1
We use micromagnetic modelling to demonstrate the operation of graded index lenses designed to steer forward-volume magnetostatic spin waves by 90 and 180 degrees. The graded index…
A note on conserved quantities for electromagnetic waves
T. G. Philbin
Electromagnetic waves carry an infinite number of conserved quantities. We give a simple explanation of this fact, which also shows how to write down conserved quantities at will a…
Contributions to single-shot energy exchanges in open quantum systems
R. Sampaio, J. Anders, T. G. Philbin +1
The exchange of energy between a classical open system and its environment can be analysed for a single run of an experiment using the phase space trajectory of the system. By cont…
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…
Some exact solutions for light beams
T. G. Philbin
We give an infinite class of exact analytical solutions for monochromatic light beams with strong focusing. As the solutions do not contain integrals, they are easy to explore comp…
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…
