复点源脉冲波束在理想导电体上的散射

Complex Source Pulsed Beams Scattering in Perfectly Conducting Cylinders

应用复射线瞬态谱理论分析了复点源脉冲波束在理想导电圆柱腔内和理想导电平面上的散射，讨论了复点源脉冲波束在理想导电平面和理想导电圆柱腔内凹曲面上的反射和散射情况。复杂的多界面导体散射体，如二面、三面角反射器与飞行器圆筒进气道等大多可由以上两种界面组成。

Based on the complex ray theory and by using the spectral theory of transient (STT),this peper discusses the reflection of complex-point source pulsed boams from a perfectly conducting plane and the scattering of complex-point pulsed beams at a perfectly conducting concave cylinder interface. By briefly reviewing the STVT,the related formulas are derived. Then scattering field of the more complicated scattering targets, such as a dihedral, a trihedral, or a cylindrical inlet, constructed by the surfaces of plane and concave,can be solved in the same way.
