  1. 1. Incoherent Scattering of Twisted Radar Beams from the Ionosphere

    University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Author : Viktor Lannér; [2017]
    Keywords : ionosphere; plasma; twisted beams; orbital angular momentum; oam effects;

    Abstract : In the search for natural orbital angular momentum (OAM) effects, some of the first incoherent scatter experiments with twisted radar beams during aurora were conducted at Poker Flat Incoherent Scatter Radar (PFISR), Alaska, USA, in October 2012. Experimental data of scatter from beam configurations with opposite twists were investigated. READ MORE

    University essay from Institutet för rymdfysik, Uppsalaavdelningen

    Author : Fredrik Waldemarsson; [2011]
    Keywords : OAM; orbital angular momentum; twisted radar beams; incoherent scattering;

    Abstract : Twenty-odd years ago, scientists managed to produce several new techniques for manipulating certain properties of laser and microwave radiation. These new properties made it possible for the radiation to contain a lot more information than what was previously known. READ MORE
