| 摘 要： | 利用电磁场的多尺度理论,将各向异性介质重构为各向同性介质,首次得到了各向异性介质圆柱体散射场和散射宽度的解析表达式,并对其有效性进行了理论验证；研究了介电常数张量等因素对散射宽度的影响；仿真结果表明,各向异性介质圆柱体的前向散射及其与入射波垂直的方向散射较强,极化方向上的介电常数对散射有着较大的影响,分析了其产生的物理...

| Abstract: | Anisotropic dielectric material was reconstructed into an isotropic medium utilizing the scales theory of electromagnetic field.The analytic expressions of scattering field and the scattering breadth for an anisotropic material cylinder were first presented.Their effectiveness was validated theoretically.The influences induced by dielectric constant tensor etc.on scattering breadth were simulated.The results showed that the scatterings both in the forward direction and vertical direction to the incident dir... |
