Angular spectrum methods constitute a powerful framework for simulating wave propagation and diffraction phenomena in optical systems. By decomposing a complex wavefield into its constituent plane ...

SIAM Journal on Numerical Analysis, Vol. 52, No. 4 (2014), pp. 2073-2091 (19 pages) In this paper, we present and analyze a new finite difference method for computing three-dimensional wave maps into ...

Experiments show that a time crystal based on magnons can interact with mechanical waves without being destroyed.

Water waves can be used to visualize fundamental concepts, such as spin angular momentum, that arise in relativistic field theory, RIKEN physicists have shown 1. This will help to provide new insights ...

A recent preprint claims that we may someday be able to create gravitational waves in a lab. Through the use of “twisted” light, we could create powerful, high-frequency waves in a controlled setting.

Sound is a form of energy. It is that form of energy which makes us hear. Sound wave is a vibratory disturbance in a medium which carries energy from one point to another without there being a direct ...
