Researchers have taken a novel approach to studying the interaction between certain topological metamaterials and sound wave propagation. The technique, described by IMDEA Materials' Dr. Johan ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. All throughout the Universe, different types of signals propagate. Some ...

We study wave propagation in a one-dimensional random medium whose index of refraction is characterized randomly and is assumed to have small fluctuations about the mean. The appropriate stochastic ...

A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...

The long-standing mystery around why spider webs sometimes feature "extra touches" known as stabilimenta has been revisited ...
