Abstract: Constructing a nearly symmetrical chiral center with tiny chiral differences is a challenging task in asymmetric synthesis. The natural antibiotic fredericamycin A (FDM-A), a representative example, has a unique structure with a quasi-symmetrical spirocyclic hydroquinone… read more here.

Abstract: In the paper, a quasi-symmetrical structure reconfigurable metasurfaces (QSRMS) is proposed to generate the full-polarization electromagnetic (EM) holographic imaging. A combination of metasurfaces and varactor that involves the position and the gap of loading varactor… read more here.
