Waves close wavesVibrations that transfer energy from place to place without the transference of matter. , including sound and light, can be reflected at the boundary between two different materials.

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...

In theory, a common feature of Mie-resonance particles is the high refractive index relative to the background medium. Although the requirement can be naturally fulfilled by a variety of ordinary ...
