Cutting-Edge Physics and Chemistry Unfold One Quintillionth of a Second at a Time
An attosecond—or 0.000000000000000001 second—is no time at all for a person. That is not so for electrons, atoms and ...
Physicists observe image rotation in plasma
Light sometimes appears to be "dragged" by the motion of the medium through which it is traveling. This phenomenon, referred ...

A new method for investigating wave propagation in optical waveguides of longitudinally invariant structures without using beam propagation algorithm - IEEE Xplore
In this paper, we propose a new method to study wave propagation in longitudinally invariant waveguides with arbitrary index profile. We keep, in the wave equation, the second order derivative of ...
