Miniaturized metamaterial-inspired antennas

The juxtaposition of materials having positive and negative effective properties allows the attainment of electrically small resonators. It has been demonstrated that these miniaturized resonators, as near-field resonant parasitic (NFRP) elements, facilitate the realization of electrically small radiators (antennas) and scatterers. A variety of metamaterial-inspired NFRP configurations from microwave to optical wavelengths will be used to illustrate the associated design concepts and their advantages in practical applications.
