Metamaterials for antennas
Metamaterials consist of dense arrays of scatterers that have a strong resonant response to magnetic fields. These novel scatterers are usually regarded as uncoupled. Our experiments (2009) revealed the first quantitative observation of magnetic dipole-dipole coupling at optical frequencies. This experiment opens completely new perspectives for magnetic and gyrotropic antennas for optoelectronics and quantum optics. We recently developed an analytical, exact, electrodynamic theory to predict the magneto-electric and chiral properties of arbitrary strongly scattering metamaterial clusters.

Figure: Split rings are very strong scatterers that have both magnetic and electric polarizability. We were the first to identify the strength of both the magnetic and electric dipole and currently develop new antennas on basis of the magnetic and chiral properties of split rings.
