Sharp trapped-mode resonances in planar metamaterials with a broken structural symmetry
TL;DR: It is reported that a resonance response with a very high quality factor can be achieved in a planar metamaterial by introducing symmetry breaking in the shape of its structural elements, which enables excitation of trapped modes, i.e., modes that are weakly coupled to free space.
Metamaterial analog of electromagnetically induced transparency.
TL;DR: It is shown that pulses propagating through such metamaterials experience considerable delay, and the thickness of the structure along the direction of wave propagation is much smaller than the wavelength, which allows successive stacking of multiple meetamaterial slabs leading to increased transmission and bandwidth.
Asymmetric propagation of electromagnetic waves through a planar chiral structure.

TL;DR: It is reported that normal incidence transmission of circularly polarized waves through the lossy anisotropic planar chiral structure is asymmetric in the opposite direction.

TL;DR: In this paper, a negative index of refraction due to three-dimensional chirality is demonstrated for bilayered metamaterial based on pairs of mutually twisted planar metal patterns in parallel planes, which also shows negative electric and magnetic responses and exceptionally strong optical activity and circular dichroism.
Toroidal Dipolar Response in a Metamaterial
TL;DR: The observation of a resonant electromagnetic response in an artificially engineered medium, or metamaterial, that cannot be attributed to magnetic or charge multipoles and can only be explained by the existence of a toroidal dipole is reported.
