Helicon wave propagation at specific angles near to the wave source in the DIII-D discharge 165908

These simulations don’t include the actual antenna geometry. The total injected power is calibrated to approximately 100kW.

Total injected power and Poynting flux at the pedestal top
Contour plot of Ez field at yz plane tilted by 5 degrees. The x-axis corresponds to the radial direction, y-axis corresponds to the toroidal direction, and z-axis corresponds to the poloidal direction. The wave source is located at (y,x)=(0,0)
