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 ...

For the first time, astronomers have caught a glimpse of shock waves rippling along strands of the cosmic web — the enormous tangle of galaxies, gas and dark matter that fills the observable universe.

A new simulation model approach called EM-Plug provides a practical path toward creating an accurate electromagnetic-based ...
