JDSU, a provider of communications test and measurement solutions and optical products, has unveiled a new medium range optical dispersion measurement (MR-ODM) module for the T-BERD/MTS (News - Alert) ...

The problem of wave propagation through a periodic medium is considered. It is assumed that the ratio between the cell size and the shortest wavelength of the initial disturbance is small. Within this ...

Zeta potential is a key indicator of the stability of colloidal dispersions and nanoparticle suspensions. It measures the electrical potential difference between the bulk of the liquid and the ...

Nothing can travel faster than light… except for sound. This is the claim of some US physicists, who say they have designed an unusual waveguide to make sound move at “superluminal” speeds (Appl. Phys ...
