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.

Aberration-free imaging for light and electrons
The equations for refraction of either the extraordinary wave of light or the wavefunction of an electron at a planar boundary between two misoriented uniaxially anisotropic materials are shown via
Negative Refraction of Electromagnetic and Electronic Waves in Uniform Media
We discuss various schemes that have been used to realize negative refraction and zero reflection, and the underlying physics that dictates each scheme. The requirements for achieving both negative
Negative refraction at deep-ultraviolet frequency in monocrystalline graphite
Negative refraction is such a prominent electromagnetic phenomenon that most researchers believe it can only occur in artificially engineered metamaterials. In this article, we report negative
Steering and collimating ballistic electrons with amphoteric refraction
We show that amphoteric refraction of ballistic electrons, i.e., positive or negative refraction depending on the incidence angle, occurs at an interface between an isotropic and an anisotropic

The concept of complementary media, which cause negative refraction and make perfect lenses, was first introduced to electromagnetic waves. This paper extends it to general waves by expressing the
