Wave Vortices Around Oscillating Subwavelength Holes: Water-Wave Observation
Junyi Ye, Zheyi Li, Alexey Y. Nikitin +4
We consider a two-dimensional wave system containing a subwavelength hole, such as an aperture in an interface supporting surface electromagnetic or acoustic waves, or an island in…
Radiation forces and torques in optics and acoustics
Ivan Toftul, Sebastian Golat, Francisco J. Rodríguez-Fortuño +3
The mechanical action of various kinds of waves has been recognized for several centuries. The first tide of scientific interest in wave-induced forces and torques emerged at the t…
Spin-Hall effect of light at a tilted polarizer
K. Y. Bliokh, C. Prajapati, C. T. Samlan +2
We describe the spin-Hall effect of light (as well as the angular Goos-Hänchen effect) at a tilted linear-dichroic plate, such as a usual linear polarizer. Although the spin-Hall e…
Acoustic Radiation Force and Torque on Small Particles as Measures of the Canonical Momentum and Spin Densities
I. D. Toftul, K. Y. Bliokh, M. I. Petrov +1
We examine acoustic radiation force and torque on a small (subwavelength) absorbing isotropic particle immersed in a monochromatic (but generally inhomogeneous) sound-wave field. W…
Angular momenta, helicity, and other properties of dielectric-fiber and metallic-wire modes
M. F. Picardi, K. Y. Bliokh, F. J. Rodríguez-Fortuño +2
Spin and orbital angular momenta (AM) of light are well studied for free-space electromagnetic fields, even nonparaxial. One of the important applications of these concepts is the…
