When waves meet a gap or an edge in a barrier, they continue through the gap or past the edge of the barrier. This may seem obvious but what happens on the far side of the gap or barrier is not so ...

Pulse measurement equipment is now easier to use than ever before, with many devices offering easy-to-align solutions and plug-and-play computer operation, reports Neil Savage. Ultrafast lasers, which ...

Abstract: The traction inverter has been extensively investigated owing to its critical role in ensuring reliable drive system performance. With the increasing emphasis on semiconductor power loss ...

Abstract: This paper proposes and demonstrates an arbitrarily tunable multi-frequency pulse modulation scheme based on an active fiber loop, which effectively suppresses the interference fading effect ...
