Backward waves leaving the metamaterial
The medium is composed of plane-parallel monolayers consisting of Huygens elements. In the molecular optics model, expressions are obtained for the reflected field, the field in the medium, and (in the case of a layer of finite thickness) behind the medium. An extinction theorem is considered, and an expression for the refractive index is introduced. Under certain conditions, such a medium can behave like a medium with a unit, zero, or negative real part of the refractive index at a given frequency. The condition for the realization of a magnetic mirror is formulated. In the case of a medium layer of finite thickness, the exit of backward waves outside the medium is shown.
