    "abstract": "Parallel permittivity elements are derived for radio frequency waves in an\naxisymmetric D-shaped tokamak with Soloviev type equilibrium under arbitrary\naspect ratio, arbitrary elongation and moderate triangularity. The\ndrift-kinetic equation is solved separately for untrapped (passing or\ncirculating) and three groups of trapped particles as a boundary-value problem,\naccounting for the transit-time and bounce resonances, respectively. It is\nshown that the new two groups of trapped particles can appear only in tokamaks\nwith large elongation and large central beta. Our dielectric characteristics\ncan be applied for both the large and low aspect ratio tokamaks with circular,\nelliptic and D-shaped magnetic surfaces to study the wave propagation and wave\ndissipation by electron Landau damping during the plasma heating and current\ndrive generation. The dissipated wave power is expressed by the summation of\nterms including the imaginary parts of both the diagonal and non-diagonal\nelements of the parallel permittivity.",
