A STUDY OF THE RIBLET COUPLER (FOR RECEPTION OF TE(O)01 MODE ENERGY BY A VEHICLE IN A TUBE)

The operation of the Riblet coupler in multi-mode round waveguide is described analytically, for the case where three TE(o)01 modes propagate in the coupling gap. A model of the coupling structure, for a vehicle flying in a tube, was built and tested, using this Riblet coupling as a basis. The coupler collected 96% of the power incident on the vehicle; however, the gap length and centering of the vehicle were more critical than expected. Details of the model and measurements are given, as well as a method for subdividing the power collected into 'packages' suitable for rectification. (Author)
