Abstract

The axisymmetric electromagnetic eigenmodes of a toroidal resonator of a circular cross-section filled with a homogeneous cold magnetized plasma are analyzed. The static magnetic field of the model considered has only a toroidal component, falling off inversely as the major radius. Since the basic equations are not separable in toroidal coordinates, they are solved by a perturbation method. Eigenfrequencies and eigenfunctions are calculated up to the second order in the inverse aspect ratio.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
