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…

Theory of Linear Spin Wave Emission from a Bloch Domain Wall
N. J. Whitehead, S. A. R. Horsley, T. G. Philbin +2
We report an analytical theory of linear emission of exchange spin waves from a Bloch domain wall, excited by a uniform microwave magnetic field. The problem is reduced to a one-di…
