Abstract

We explore the issue of interactions between metamaterial resonators and different types of absorbers placed in proximity to these resonators. Very clear anticrossing behaviour and level splitting is observed when IR phonons interact with planar metamaterials. More complex dipole transitions can be designed using semiconductor bandgap engineering. We show experimentally the coupling between metamaterial resonances and intersubband transitions and discuss this mechanism for electrical tuning of metamaterials throughout the optical infrared spectral region. Finally we will discuss interactions in 3D dielectric resonator metamaterials.
