Published in 2018 at "Journal of Physical Chemistry C"

DOI: 10.1021/acs.jpcc.7b10417

Abstract: Metamaterials have attracted considerable attention owing to their extraordinary ability in controlling the propagation of electromagnetic waves. These materials can be realized using artificial composites consisting of subwavelength metallic resonators, but losses of the metallic… read more here.

Published in 2020 at "Micromachines"

DOI: 10.3390/mi11070641

Abstract: We propose a thin, single-layered circular dichroic filter with Au nanospiral structures on a polydimethylsiloxane (PDMS) thin film that has strong circular dichroism at visible wavelengths. Au nanospiral structures with a diameter of 70 nm… read more here.
