Full Wave 2D Theory of LH Grills Suitable for Large Structures
Original language description
Lower hybrid waves are very important for heating and current drive in contemporary tokamaks.Phased arrays of rectangular waveguides are frequently used as launcher. While the simple theory of parallel plate waveguide coupling to the plasma slab with thelinear density profile was successful [1],it neglected the coupling of the fast to slow wave in the inaccessibility region and could not handle the effect of the poloidal field. These drawbacks were overcome by 2D grill theory assuming rectangular waveguides and the full wave solution in the plasma [2].However, this method is rarely used for large structures as it requires the evaluation of a very large number of 2D infinite integrals in k-space [3].Here,we overcome this drawback by using high order Gaussian quadratures and 2D B-splines of the integrands in N-pol,N-tor-space.We adopt efficient and accurate methods of handling the eigenmodes excited by the LH grill in the inaccessible N-tor -region and clarify the role of collisions.
