There is a growing interest in plasmonics in recent years, on one hand motivated by the need to understand and control the behavior of light below the diffraction limit, and on the other by its potential applications in devices, sensing, giant field enhancement, negative index materials, and many others. Assuming that the appropriate materials will be found, or designed, along with practical structures, it is expected that the field of plasmonics has a potential to also revolutionalize the microelectronics industry. Currently, the main issue that halts the application of plasmonics are losses in metals that affect the performance of every plasmonic structure. At present, main conventional plasmonic materials used in plasmonics are gold and silver because of their relatively small ohmic losses when compared with other metals. However, the existing losses in those materials are still one of the major problems in using those metals in plasmonics.
