Abstract
Silver metal is known to share some of the peculiar features of metamaterials in optical frequency domain. In this article, we investigate the occurrence of negative and/or orthogonal phase velocity, negative refraction and counterposition phenomena in silver with fractional dimensions. For this purpose an interface of free space and silver metal is considered for various values of fractional dimensions of both the half spaces. The observed values of the refracted poynting vector relate to the occurrence of the above mentioned phenomena. It is noted that although the fractionality of either of the half space does not alter the occurrence of the said phenomena, the absolute values of the refracted poynting vector vary greatly with a change in the fractionality of dimensions, indicating a possible control of energy flow in refracted fields via fractional parameters.
