发现存在一类容易获得的材料界面，其不仅可以提供全折射（即，零反射）但也可引起两性折射（即，正折射和负折射），用于任何频域中的电磁波以及弹道电子波。这两个不寻常的现象证明了实验的光通过这样的界面的传播。
It is found that there exists a category of material interfaces, readily available, that not only can provide total refraction (i.e., zero reflection) but can also give rise to amphoteric refraction (i.e., both positive and negative refraction) for electromagnetic waves in any frequency domain as well as for ballistic electron waves. These two unusual phenomena are demonstrated experimentally for the propagation of light through such an interface.
