Abstract
AbstractWe report on a new kind of planar left‐handed metamaterial with both simulations and experiments in this article. Dual electric and magnetic resonance frequency bands are experimentally realized by introducing two different metallic elements in one unit cell, which offers a convenient approach in building dual‐band or multiband negative‐index metamaterials. The effective electromagnetic parameters obtained from the measured S‐parameters indicate that negative refractive indexes are verified near 8.5 and 12 GHz with both negative permittivity and negative permeability. Field and current distribution at the dual resonances are also examined. At last, we calculated the radiated power of the magnetic dipole moments along y‐axis. The idea can help us to fabricate dual‐band or multiband metamaterial absorbers, filters, and antennas. © 2012 Wiley Periodicals, Inc.
