1)研究了双各向异性特异材料(bianisotropic metamaterials)的本构关系(constitutive relations),基于透射和反射系数,倒推出本构关系中的有效参数(介电常数,磁导率,和电磁耦合系数),得到简洁的公式。成果发表在2009年的Physical Review E,目前他引用超过130次。

2)研究了平面(二维)手性纳米结构在红外波段的非对称透射现象。构建了等价的光学集总元件模型(optical lumped element model),并推导出简明的公式。首次提出通过改变损耗系数的各向异性来操纵平面手性纳米结构的非对称透射的大小程度。成果发表在2013年的Advanced Optical Materials1卷。

3)设计并研究了亚波长孔径中透射的电磁波经过径向光栅的散射形成类似贝塞尔波束的现象。成果发表在2009年的Physical Review Letters
