Anomalous reflection of electromagnetic waves at O-X mode conversion in 2D inhomogeneous turbulent plasma

摘要

Anomalous reflection of electromagnetic waves at linear O-X mode conversion in 2D inhomogeneous turbulent plasma is investigated. The problem is treated assuming the density fluctuation level is low enough that the Born approximation is still applicable. Accounting for the two-dimensional side-scattering effects a criterion on the plasma density fluctuation level exceeding which the Born approximation is no longer valid and the anomalous reflection appears to be substantial, is derived.
