Flat Optics With Designer Metasurfaces
Nanfang Yu,Federico Capasso +1 more
TL;DR: This Review focuses on recent developments on flat, ultrathin optical components dubbed 'metasurfaces' that produce abrupt changes over the scale of the free-space wavelength in the phase, amplitude and/or polarization of a light beam.
Journal ArticleDOI
Extremely Low Frequency Plasmons in Metallic Mesostructures
TL;DR: A mechanism for depression of the plasma frequency into the far infrared or even GHz band is proposed: Periodic structures built of very thin wires dilute the average concentration of electrons and considerably enhance the effective electron mass through self-inductance.
