A totally new way to measure radio signals from space

Scientists from the research programme PHISP (Physics in Space) at IRF in Uppsala have published an article on a totally new way to measure radio signals from space. The article "Utilization of Photon Orbital Angular Momentum in the Low-Frequency Radio Domain", Bo Thidé, Jan Bergman et al., has been published in Physical Review Letters vol. 99, no. 8 (24 August 2007): One of the figures from the article appears on the cover of the journal.

The Swedish Institute of Space Physics (IRF) is a governmental research institute which conducts research and postgraduate education in atmospheric physics, space physics and space technology. Measurements are made in the atmosphere, ionosphere, magnetosphere and around other planets with the help of ground-based equipment (including radar), stratospheric balloons and satellites. IRF was established (as Kiruna Geophysical Observatory) in 1957 and its first satellite instrument was launched in 1968. The head office is in Kiruna (geographic coordinates 67.84° N, 20.41° E) and IRF also has offices in Umeå, Uppsala and Lund.
