Generalising the Yagi-Uda Antenna: Designing Disordered Metamaterials to Manipulate Antenna Radiation
J. R. Capers, L. D. Stanfield, J. R. Sambles +4
Next generation microwave communications systems face several challenges, particularly from congested communications frequencies and complex propagation environments. Taking inspir…
Superfluid Optomechanics with Phononic Nanostructures
S. Spence, Z. X. Koong, S. A. R. Horsley +1
In quantum optomechanics, finding materials and strategies to limit losses has been crucial to the progress of the field. Recently, superfluid 4He was proposed as a promising mecha…
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 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…
