Electron cyclotron (EC) wave power losses tend to play a significant role in the local electron power balance of a tokamak fusion reactor for electron temperatures above 35 keV as considered for steady-state operation. Using the RAYTEC code a compara

On the basis of the electromagnetic energy balance equation, a quasi-exact analytical evaluation of the electron-cyclotron (EC) absorption coefficient is performed for arbitrary propagation (with respect to the magnetic field) in a (Maxwellian) magne

In the context of electrodynamics of continuous media, the electromagnetic response of a generic medium is usually described in terms of the polarization and magnetization fields P (r, t) and M (r, t), the physical content of which is connected to th

The angular dependence of the electron cyclotron (EC) absorption in a high-temperature plasma ( T e ≳ 20 keV ) is revisited on the basis of analytical expressions for the EC absorption coefficients of both the extraordinary and ordinary mode obtain

The importance of electron cyclotron (EC) wave emission to the local electron power balance is analysed for various ITER operation regimes and, for comparison, for typical working conditions of FIRE, IGNITOR and the reactor-grade ITER concept as cons

An exact analytical solution of the equation of radiative transfer is obtained for a cylindrical system with specularly reflecting walls, accounting for the presence of polarization scrambling in the reflection process. The effects of polarization sc

Two forms of the transport equation for the wave energy density inherent in two (apparently diverse) formulations of geometrical optics (GO) are discussed on the basis of the relationships among the plane-wave dielectric tensor, the effective dielect
