Electromagnetic Waves in Metallic Wire Structures
With the advance of nanofabrication technology, more and more artificial materials have been proposed and developed in the past 20 years. Two representative examples are photonic and phononic crystals. The existence of the forbidden gap makes it possible to manipulate and control the flow of electromagnetic (EM) and acoustic waves. More recently, the focus has switched to metallic wire structures. Macroscopic metallic wire structures have been much studied in the past, partly connected with antenna applications. Recently, EM composite materials with metallic wire components have received much attention.
