Abstract

In this study, plasmonic nanoscatter-based metacells supported with tungsten disulfide will be analyzed in terms of phase gradient. Numerical analyzes are made for the design of nanoscatterers using the finite difference time domain method. In this context, first, the non-rotational and rotational resonant behavior of gold nanoscatterers in the optical spectrum, which is determined as the basic nanoantenna, is examined. At the considered resonant wavelength, the effect of the versions derived from basic nanoantenna structure supported by tungsten disulfide and rotated, on the phase gradient is analyzed. Here, since tungsten disulfide layers have large transmittance values in visible spectral ranges, it is expected to increase resolution in phase.
