Resonant absorption in a exponential electronic density gradient
Description
We use the capacitor model to study resonant absorption in a hot, unmagnetised, Maxwellian, inhomogeneous plasma. We integrate the linearised Vlasov equation to get a non local dispersion relation for the Fourier transform of the electric field. We solve this dispersion relation in two domains of the wave number, klambdasub(D). For weak gradients of the electron density, we correct the hydrodynamic equations by adding a Landau damping term. For steep gradients, we solve the dispersion relation numerically
