Our goal is to present a large group of optical phenomena observed in anisotropic nanostructures such as nanowires (NWs) and nanorods (NRs) placed in an environment with a dielectric constant ?0 different from that of the nanostructure ?. Actually, this situation occurs for most experimental work on NWs and NRs. For instance, in recent years, a large number of works have emerged devoted to the fabrication and the investigation of NWs grown in a free-standing fashion from catalyst particle nano-islands (Duan and Lieber 2000), or in a dielectric template with cylindrical pores (Mei et al. 2003), as well as for solution-grown NRs (Peng et al. 2000). Since the dielectric constant of the semiconductor ? is usually of the order of 10 or larger, this situation is realized for NWs and NRs free-standing in air, dissolved in liquids, or embedded in most dielectric matrices. Such effects of dielectric mismatch are observed not only for the semiconductor but also for metal nanostructures, where ? also differs noticeably from ?0 and, besides, has a complex character and a strong frequency dispersion.
