METAMATERIALS AND THEIR RF PROPERTIES

摘要

The emerging field of electromagnetic metamaterials has matured to the point where they are receiving serious consideration for use in antenna and other RF applications. Here, we present background on how metamaterials science and technology has evolved and on what benefits metamaterials promise for antenna applications and transmission lines, especially in the GHz to THz frequency range. The important issues of bandwidth and dispersion, THz applications, energy loss within the metamaterial, polarization effects, and potential antenna gain are discussed.
