EM scattering analysis of laser plasma channel antenna in a finite magnetic field

XIA Xin-ren, YIN Cheng-you (State Key Laboratory of Pulsed Power Laser Technology, Hefei Electronic Engineering Institute, Hefei 230037)  
The scattering characteristic of an obliquely incident plane electromagnetic wave by laser plasma channel antenna (LPCA) in a finite magnetic field is discussed and the electromagnetic model of LPCA in a finite magnetic field is created. Using the cylindrical coordinate and anisotropic magnetized plasma model, the wave equations of the longitudinal components and the relationships between transverse and longitudinal component are derived, the electromagnetic fields in LPCA and in the medium are given, and the equations of scattering coefficient are deduced. The calculation shows a good agreement with the result given in the reference and a possible application in the study of high power microwave weapon.
