Abstract
The properties and applications of different types of ceramic all-dielectric metamaterials are presented. Metamaterials composed of arrays of identical ceramic resonators are shown to provide for negative refraction, enhanced transmission, and backward wave propagation. It is also demonstrated that arrays of dielectric elements can be used as non-resonant metamaterials to form a gradient index medium. Employment of such media in antenna substrates is shown perspective for antenna miniaturization without deteriorating antenna parameters. The development of a microwave transmission cloak composed of identical low-loss ceramic resonators to conceal object with the dimensions far exceeding the wavelength of incident radiation is also described.
