Nearly perfect, ultrathin invisibility cloak could have wide practical applications
Magnetic shell provides unprecedented control of magnetic fields
Ex nihilo: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons
Physicists demonstrate first time reversal of water waves
Fantastic phonons: Blocking sound, channeling heat with 'unprecedented precision'
Imagine living on a bustling city block, but free from the noise of car horns and people on the street. The emerging field of phononics could one day make this a reality.
Scientists create perfect solution to iron out kinks in surfaces
A new technique that allows curved surfaces to appear flat to electromagnetic waves has been developed by scientists at Queen Mary University of London.
Invisibility cloak that generates virtual images gets closer to realization
Physicists build quantum amplifier with single artificial atom
Making a better invisibility cloak
The first functional "cloaking" device reported by Duke University electrical engineers in 2006 worked like a charm, but it wasn't perfect. Now a member of that laboratory has developed a new design that ...
Scientists spin photons to send light in one direction
(Phys.org) —Researchers at King's College London have achieved previously unseen levels of control over the travelling direction of electromagnetic waves in waveguides. Their ground-breaking results could ...
