Abstract:

A method for realizing dualband left-handed metamaterials is presented. By integrating the magnetic resonator plus wire with the magnetic resonator, a novel left-handed metamaterial based on the Oblique triangular open-loop pairs resonator (OTOR) is presented. By analyzing the distribution of the surface current, electric field and equivalent circuit, the combined structure exhibits double LH passbands. The first LH passband is decided by the OTOR+Wire, while the second LH passband is decided by the OTOR. Simulation and experimental results and analysis verify this design. Furthermore, the idea can help us to design negative-index materials with multibands.

Key words: left-handed matamaterials, oblique triangular open-loop pairs resonator (OTOR), dualband, transmission experiments
