Description
The electric/magnetic fields generated on the surface of a dense plasma by hot electrons are considered with relativistic fluid theory. Quasi-steady state solutions are considered with both isothermal and isentropic models and conservation laws for the electron flows in terms of the four-potential and specific enthalpy. We find analytic solutions for the electric and magnetic field profiles and compare to particle-in-cell simulations, showing good agreement. The analytic model delineates refluxing and surface confinement regimes for the hot electrons. The results should be relevant to ion acceleration and magnetic field generation.
