Physicists have finally confirmed a phenomenon that sounds like pure science fiction: waves that appear to bounce off a sudden change in time rather than a surface in space. The effect, known as a ...

Fig. 2. The model of electromagnetic wave incident on 3D surface. Fig. 3. Model of an asteroid under incident electromagnetic waves. Rotation angle of the asteroid: ① β= 0°; ② β= 30°; ③ β= 90°. Fig. 4 ...

(Nanowerk Spotlight) Controlling how electromagnetic waves behave as they move through space is essential for technologies like wireless communication, radar, and remote sensing. Engineers have ...
