Electromagnetic interference is everywhere, coming from appliances and electrical systems. Now a team from Microsoft Research wants to harness this unorganized ambient noise as an affordable way to ...

Today when we send information -- speech, words, numbers, or pictures -- to someone far away we can use the radio, telephone, television, fax machine, or a computer network. However, the need for ...

The Air Force is working with Raytheon to integrate high power electromagnetic (HPEM) capabilities with cyber and electronic warfare weapons systems to increase the effectiveness of EW weapons through ...

The ability to control wave propagation is of fundamental interest in many areas of physics. Photonic crystals proved very useful for this purpose but, because they are based on Bragg interferences, ...

In controlled experiments, engineers have shown that electricity can be transmitted through the air using highly controlled ...

For radioastronomers, the far side of the Moon could be the last unspoilt refuge in the Solar System. Planet Earth — and all the human-made electromagnetic noise it spews out into space — stays ...

Air Force officials at Kirtland Air Force Base, N.M. are working with microwave experts from companies including Raytheon and Booz Allen Hamilton to conduct experiments with high power electromagnetic ...

A background buzz of electromagnetic waves from such ordinary sources as electronic equipment can interfere with a bird’s magnetic compass, according to a particularly careful set of experiments.
