It is also demonstrated that the negative permittivity and permeability frequency band of DNM could be turned by changing the DNM structure cell. 通过改变双负材料的结构单元可以实现对负介电常数和负磁导率频段的调控。
Its morphological structure unit is a rodlike macromolecule which drrdnges regularly to form domdins, then these domains pack further to form a rodlike submicroscopic structure. 其形态结构单元是由棒状分子规整排列形成的微区。
