Paper Abstract

Contrarily to classic Right-Handed Materials (RHMs), the role of losses is crucial for composite materials called metamaterials such as Ultra-refractive Right-Handed Materials (URHMs) and Left-Handed Materials (LHMs). As the loss-free case for a metamaterial is not stable, a small variation of losses can drastically modify the expected properties of such a material. Thus, it is important to understand how the input of lossy term affects URHM and LHM aspects, and also to define, for each of them, the tolerance level for which the interesting metamaterial properties are still valid. The role of losses is investigated analytically and numerically, a full study about the action of the losses on all the properties is done. It is shown that those properties almost completely disappear for an LHM slab with loss tangent over 0.01, which at optical frequencies corresponds to a good material.
