Spin- and orbital-Hall effect in cyclic group symmetric metasurface
Yeon Ui Lee, Igor Ozerov, Frederic Bedu +3
Light possesses both spin and orbital angular momentum (AM). While spin AM is determined by helicity of circular-polarization, orbital AM is characterized by topological charge of…

Transmission enhancement through square coaxial apertures arrays in metallic film: when leaky modes filter infrared light
Benjamin Vial, Frédéric Bedu, Hervé Dallaporta +6
We consider arrays of square coaxial apertures in a gold layer and study their diffractive behavior in the far infrared region. These structures exhibit a resonant transmission enh…
