  Parallel permittivity elements are derived for radio frequency waves in an
axisymmetric D-shaped tokamak with Soloviev type equilibrium under arbitrary
aspect ratio, arbitrary elongation and moderate triangularity. The
drift-kinetic equation is solved separately for untrapped (passing or
circulating) and three groups of trapped particles as a boundary-value problem,
accounting for the transit-time and bounce resonances, respectively. It is
shown that the new two groups of trapped particles can appear only in tokamaks
with large elongation and large central beta. Our dielectric characteristics
can be applied for both the large and low aspect ratio tokamaks with circular,
elliptic and D-shaped magnetic surfaces to study the wave propagation and wave
dissipation by electron Landau damping during the plasma heating and current
drive generation. The dissipated wave power is expressed by the summation of
terms including the imaginary parts of both the diagonal and non-diagonal
elements of the parallel permittivity.
