CEM Based on Finite-Volume Time Domain Method

介绍了基于计算流体力学(CFD)中的时域有限体积法(FVTD)的电磁计算。根据Maxwell方程组,给出了计算电磁(CEM)中FVTD的时间离散、MUSCL迎风型格式插值、空间离散和边界条件的处理,以及雷达散射截面(RCS)的计算公式。对无限长理想导体圆柱和线天线二维完全导电体的表面诱导电流与雷达散射截面计算结果表明:FVTD是一种高效准确的时域有限方法。

Computational electromagnetics based on finite-volume time domain method(FVTD) of the computational fluid dynamics(CFD) was introduced in this paper.The time dispersing,MUSCL windward format interpolation,space dispersing and boundary condition were presented according to Maxwell equations.The equation of radar cross section was established.The computation of surface inducted current density and radar cross section of infinity ideal circular cylinder and linear antenna showed that FVTD method was a high eff...
