| 摘 要： | 为分析尖劈形材料的吸波性能,建立了半圆镜像模型将辐射波在尖劈空间的传播等效为射线对等分半圆的切割,确定了反射波线和吸波材料几何参数之间的解析关系.对于微波暗室问题,假设在余弦辐射体上随机选取一个方向的能量波束集中了其所有能量,分别建立了加权能量分布模型和Monte Carlo模型,仿真验证了两模型结论的一致性.

| Abstract: | To evaluate the performance of wedge-shaped material absorbing,firstly we develop a semi-circular mirror model simpling the complex reflections of the radiation wave in the wedge space as a radiation path line decile semicircle cutting equivalently.To study anechoic chamber,based on analyzing the distribution of remained radiations in the anechoic chamber walls after the first reflection of the antenna radiation energy,we separately model the problem by weighted energy distribution and Monte Carlo methods.Simulation results show that the two method are almost equal. |
