Physicists Find Evidence of , 'Time Reflections'.
Physicists at the City University of New York's Advanced Science Research Center (CUNY ASRC) have put the theory of 'time reflections' into practice.
ScienceAlert reports that the researchers have provided the first evidence of manipulations across the electromagnetic spectrum.
This has been really exciting to see, because of how long ago this counterintuitive phenomenon was predicted, and how different time-reflected waves behave compared to space-reflected ones, Andrea Alù, physicist and founding director of the CUNY ASRC Photonics Initiative, via ScienceAlert.

According to ScienceAlert, the achievement could have implications for fields that include imaging, analog computing and optical filtering.

Using a sophisticated metamaterial design, we were able to realize the conditions to change the material's properties in time both abruptly and with a large contrast, Andrea Alù, founding director of the CUNY ASRC Photonics Initiative, via ScienceAlert.

Metamaterials are designed with unique properties that target a specific purpose to suit different needs that are structural, acoustic or optical.
