  • 摘要: 该文提出了基于无源介质谐振器腔内磁偶极子谐振的准超方向性再辐射,旨在增强薄导电板受到平面电磁波侧向照射时的后向散射截面。在平面电磁波激励下,设计适当的长方介质体中可诱导产生具有磁偶极子再辐射特征的混合电磁谐振模式。以长方介质体为基本谐振单元,将两个相同的介质体沿入射波传播方向紧密级联以组成一个超单元。超单元的两个介质体中的磁场强度与电场强度矢量均呈现相反的方向且相近的幅度,接近等幅而反相的内部场分布使超单元类似一个二元准超方向性磁偶极子阵列,由此产生的准超方向性再辐射有效地贡献于后向散射截面增强。进一步,由镜像原理,将超单元剖面厚度减半并加载于薄导电板表面。结果表明,剖面厚度仅为0.078λ0的介质谐振器形成基于磁偶极子的准超方向性再辐射,在谐振频率处可显著修改薄导电板的侧向回射特性,进而在相对宽带宽角范围内对侧向入射波实现有效的后向散射截面增强。
