Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional ...

internal reflection of light vanishes due to spatial confinement, leading to one-directional straight propagation of light. Consequently, the light emission pattern becomes highly directional.

While it has long been possible to selectively filter light according to its color or polarization, selectivity based on the direction of propagation has remained elusive. But now, for the first ...

It discovered that the addition of the LEGO resonators makes wave propagation in the plate highly directional at particular ...

It discovered that the addition of the LEGO resonators makes wave propagation in the plate highly directional at particular frequencies and that adjusting the twist angle may allow remarkable control ...
