✦ Synopsis

A variational principle is presented for ICRF heating calculations in real tokamak geometries with the minimum assumptions on the electromagnetic potential field structure. Different regimes for the ratio A/AC of the parallel scalelength of the field A and of the parallel scalelength of the resonance A~can be studied. We also present a finite element method for the numerical computation of the field and of the power deposition profiles in the ion cyclotron range of frequencies.
