LATEST NEWS

2011-11-16 In a laboratory experiment we have demonstrated how a radio (or radar) beam that is reflected off a target whose refractive properties varies perpendicularly relative to the radio/radar beam axis becomes "twisted", i.e. contains photon orbital angular momentum (OAM). As demonstrated in the article Experimental verification of photon angular momentum and vorticity with radio techniques in the November, 2011 issue of Applied Physics Letters it is possible to decide this azimuthal structuring of the refractive medium, e.g., a plasma, by analysing the OAM spectrum, also known as the spiral spectrum, of the reflected beam (radar echo).
2011-10-28 Erik Nordblad successfully defended his doctoral thesis Opening New Radio Windows and Bending Twisted Beams.
