Abstract: In this paper, a single-layer, low-profile, broadband shared-aperture composite metasurface is proposed. It consists of a Ka-band reflect-array and an X-band phased-array antenna with ...

Their findings were published in Physical Review Letters in a paper titled “Enabling all-to-circular polarization up-conversion by nonlinear chiral metasurfaces with rotational symmetry.” The team’s ...

Generation of circularly polarized nonlinear signals from chiral metasurfaces with rotational symmetry under arbitrarily polarized excitation. (Image: SUTD) The team’s proposed metasurface exhibits ...

Through mathematical elucidations, the team demonstrated that the stacking of layers leads to the chiral response of the metasurface. "Just two stacked layers can yield a maximally chiral response ...

Despite their potential, many metasurface-based antennas have so far achieved underwhelming results, such as low data transmission rates and poor information mapping efficiencies. "In previous works, ...

This work investigates handedness-dependent two-photon absorption effect of a chiral metasurface, which comprises periodic asymmetric split ring amorphous silicon (α-Si) nanostructure atop, an ...
