Anomalous skin effect for anisotropic electron velocity distribution function

The anomalous skin effect in a plasma with a highly anisotropic electron velocity distribution function (EVDF) was discussed. It was observed that highly anisotropic EVDF yielded a large skin layer depth compared with the isotropic EVDF. The anisotropic EVDF was related to Weibel instability, which developed quickly during the penetration of the electric field into the plasma. The numerical integration of the inverse Fourier transform confirmed that the skin layer exhibited multiple oscillations of the electric field.
