2010 (English)In: Radio Science, ISSN 0048-6604, E-ISSN 1944-799X, Vol. 45, RS4007- p.Article in journal (Refereed) Published
Novel measurement and approximation methodologies for studying orbital angular momentum (OAM) modes in radio beams, i.e., electromagnetic beam modes having helical phase fronts, are presented. We show that OAM modes can be unambiguously determined by measuring two electric field components at one point, or one electric field component at two points.
