The ability to control wave propagation is of fundamental interest in many areas of physics. Photonic crystals proved very useful for this purpose but, because they are based on Bragg interferences, ...

sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them to ...

Types of Waves: In Physics, waves are a fundamental phenomena that describes the transmission of energy and information through a medium of an empty space. These waves are characterised by their ...

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 ...

Michael Hall receives funding from the Australian Research Council and the Foundational Questions Institute. We see them at the beach. They’re behind every sound and light show and the miracle of ...

IT is well known 1 that the velocity of propagation of an electromagnetic signal is governed by the boundary conditions imposed by the guiding structure, the type of modulation and the characteristics ...
