Theory of transverse waves in Vlasov-plasmas
The problem of reflection of normally incident electromagnetic waves by a plasma half-space is solved. The equilibrium plasma is supposed to be spatially homogeneous and isotropic in velocity space, the particles are assumed to be reflected specularly at the plane boundary From the multitude of stationary solutions, compatible with the latter assumption, one is selected by imposing a causality condition. The exact reflection coefficient found from this solution is compared with the results predicted by the Fresnel formula with the aid of the refractive index, the present problem leads to a natural extension of the definition of the refractive index to the range of frequencies smaller than the plasma frequency. The relation to the theory of the anomalous skin effect in metals is also discussed.
