Metamaterials have recently enabled coupling induced transparency due to interference effects in coupled subwavelength resonators. In this work, we present a three dimensional (3-D) metamaterial design with six-fold rotational symmetry that shows electromagnetically induced transparency with a strong polarization dependence to the incident electromagnetic… (More)
We investigate resonant transmission of planar asymmetric metamaterials made from double split-ring resonators. More than 50% amplitude modulation is observed at the fundamental inductive-capacitive resonance due to circular polarization conversion.
