WebThe R wave and the L wave are right-hand and left-hand circularly polarized, respectively. The R wave has a cut-off at ω R (hence the designation of this frequency) and a resonance at ω c. The L wave has a cut-off at ω L and no resonance. R waves at frequencies below ω c /2 are also known as whistler modes. Dispersion relations WebDescription: ENCUT specifies the cutoff energy for the plane-wave-basis set in eV. All plane waves with a kinetic energy smaller than are included in the basis set, i.e., The number of plane waves differs for each k -point, leading to a superior behavior for, e.g. energy-volume calculations. If the volume is increased the total number of plane ...
