What does a dispersion relation for a wave in plasma describe?
Dispersion relation. Dispersion relation provides a relationship between the wave vector and the frequency of a wave and describes under which conditions the wave can propagate and under which conditions it cannot propagate.
What is dispersion electromagnetic waves?
Dispersion occurs when sinusoidal waves of different wavelengths have different propagation velocities, so that a wave packet of mixed wavelengths tends to spread out in space.
What is plasma dispersion function?
If the unperturbed distribution function, , appearing in Eq. ( 1007), is a Maxwellian then it is readily seen that, with a suitable scaling of the variables, the dispersion relation for electrostatic plasma waves can be expressed in terms of the function.
What is dispersion relation formula?
dispersion relation ω = ω(k) then the complete solution can be written. u(x, t) = ∫ ∞ −∞ A(k)eikx−iω(k)t dk.
