有耗介质圆柱双站RCS分析及比较

Analysis and Comparison of Bistatic RCS of the Dissipative Dielectric Cylinders

对于不同的复介电常数,给出了有耗介质圆柱双站RCS的矩量法解,并与解析法进行了比较.仿真结果表明:圆柱谐振区的散射最强;介质的介电损耗因子代表了介质的吸波性能;不同频率的入射波,截面分割单元的电长度影响矩量法的计算精度.

The paper analyzes the bistatic RCS of the dissipative dielectric cylinders with different com-plex permittivity by using the moment methods, and compares it with the analytics. The results show that there is strong scatter in resonance region; the dielectric lose gene represents the wave-absorbed performance of the material; with the different frequency incidence waves, the electric size of the cell affects the precision of the moment methods.
