摘要: Wakefield excitation in a preformed inhomogeneous parabolic plasma channel by an intense relativistic (≃1019 W/cm2) circularly polarized Gaussian laser pulse is investigated analytically and numerically the presence of external longitudinal magnetic field. A three dimensional envelope equation for evolution derived, which includes effect nonparaxial applied relation radius with spot size derived examines to see field effect. It observed that depends on An analytical expression wakefield validated help two particle cell (2D PIC) simulation code. shown electromagnetic nature wakes makes their nonlocal, results change fields time due phase mixing ...
