First experimental observation of matter-wave diffraction in a short-lived electron-positron atom using a graphene-based diffraction grating. (Nanowerk News) One of the discoveries that fundamentally ...
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 ...
Researchers developed a model showing the ability of reconfigurable intelligent surfaces to redirect the propagation of radio waves, which could improve the signal. A method to analytically express ...
A method to analytically express the performance of wireless communication systems when using reconfigurable intelligent surfaces (RIS) was successfully developed by researchers at Tohoku University, ...
