BDM, broadband dielectric mirror; PPKTP crystal, periodically polarized KTiOPO4 crystal; DPBS, dual-wavelength polarization beam splitter; PBS, polarization beam splitter; DM, dichroic mirror; FC, fiber coupler; BPF, band-pass ...
phase and amplitude of the two orthogonal polarization components by designing the Jones matrixT(x,y)of metasurfaces. For instance, if the four complex coefficients of the Jones matrixT(x,y)can be independently manipulated, optical multiplexing with four polarization channels can be achieved by con...
The interplay between resonant modes can lead to strong effects on the particle scattering properties, including directional radiation effects [56], ad-hoc beam shaping [62], beam phase control for Huygens´ metasurfaces [107] and perfect absorption [108]. Indeed, in the case of overlapping ...
Metasurfaces can be used to perform optical functions such as focusing and beam steering via the resonant scattering of arrays of nanoscale scatterers fabricated on a flat surface [99], such as that exhibited in Fig. 23(a). By controlling the widths of the pillars on the substrate, both ...

Optical metasurfaces (OMs) have emerged as promising candidates to solve the bottleneck of bulky optical elements. OMs offer a fundamentally new method of light manipulation based on scattering from resonant nanostructures rather than conventional refraction and propagation, thus offering efficient phase, ...
“Revealing the origins of angular dispersions in metasurfaces”. Neglecting the influences of the metallic back plane, we understand that the radiation power of the magnetic dipole should be proportional to\(\cos ^2\theta\)due to the transverse nature of the radiated EM waves (see Fig.S7for...
