Description

An analytical solution of the wave equation including toroidal effects, inhomogeneity, shear, and finite Larmor radius effects is given for the description of wave absorption in the ion-cyclotron radiofrequency regime. The result shows that toroidal and inhomogeneity effects change the wave field profile by an amount of the order of the local aspect ratio, while shear and inhomogeneity effects together determine the eigenfrequencies. The plasma beta ratio in tokamak devices seriously modifies the eigenfrequency spectrum. 1 ref
