In the beam of light emitted by a laser pointer, photons travel predominantly along one direction and the beam is therefore said to be collimated. The electric field carried by these photons is ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

For transverse loading of the composite, the components experience the same stress and for this isostress situation the total transverse strain of the composite is just the sum of the fiber strain and ...
