Physicists Find Evidence of , 'Time Reflections'.<br />Physicists at the City University of New York's <br />Advanced Science Research Center (CUNY ASRC) have <br />put the theory of 'time reflections' into practice.<br />ScienceAlert reports that the researchers <br />have provided the first evidence of manipulations <br />across the electromagnetic spectrum.<br />This has been really exciting <br />to see, because of how long ago <br />this counterintuitive phenomenon <br />was predicted, and how different <br />time-reflected waves behave <br />compared to space-reflected ones, Andrea Alù, physicist and founding director of <br />the CUNY ASRC Photonics Initiative, via ScienceAlert.<br />This has been really exciting <br />to see, because of how long ago <br />this counterintuitive phenomenon <br />was predicted, and how different <br />time-reflected waves behave <br />compared to space-reflected ones, Andrea Alù, physicist and founding director of <br />the CUNY ASRC Photonics Initiative, via ScienceAlert.<br />According to ScienceAlert, the achievement <br />could have implications for fields that include <br />imaging, analog computing and optical filtering.<br />According to ScienceAlert, the achievement <br />could have implications for fields that include <br />imaging, analog computing and optical filtering.<br />Using a sophisticated metamaterial <br />design, we were able to realize the <br />conditions to change the material's <br />properties in time both abruptly <br />and with a large contrast, Andrea Alù, founding director of the CUNY ASRC <br />Photonics Initiative, via ScienceAlert.<br />Using a sophisticated metamaterial <br />design, we were able to realize the <br />conditions to change the material's <br />properties in time both abruptly <br />and with a large contrast, Andrea Alù, founding director of the CUNY ASRC <br />Photonics Initiative, via ScienceAlert.<br />Metamaterials are designed with unique properties <br />that target a specific purpose to suit different <br />needs that are structural, acoustic or optical. .<br />The exotic electromagnetic <br />properties of metamaterials <br />have so far been engineered <br />by combining in smart ways <br />many spatial interfaces, Shixiong Yin, physicist and one of <br />the study's lead authors, via ScienceAlert.<br />The exotic electromagnetic <br />properties of metamaterials <br />have so far been engineered <br />by combining in smart ways <br />many spatial interfaces, Shixiong Yin, physicist and one of <br />the study's lead authors, via ScienceAlert.<br />Our experiment shows that it is <br />possible to add time interfaces into <br />the mix, extending the degrees <br />of freedom to manipulate waves, Shixiong Yin, physicist and one of <br />the study's lead authors, via ScienceAlert.<br />The team's work was published in 'Nature Physics.'
