Abstract / Description of output

In this paper the detection of Orbital Angular Momentum (OAM) modes at a carrier frequency of 10 GHz is evaluated by modelling and by experimentation. A 2-element antenna array together with the phase gradient detection method are used to determine whether a mode 0 or -1 is present, where our results verify that a distinct difference in measured phase profile between the two modes is distinguishable even in the presence of a multipath reflection. The measured influence of the multipath reflection is shown to agree well with modelling results. Our model combines full-wave simulations of transmit and receive antennas with a ray tracing model, revealing the respective influence of the direct and reflected multipath components of the signal. Consequently, our work shows novel insights confirming the behaviour of an OAM radio signal with a dominant reflected component and subsequent performance of the detector through experimentation.
