Herein, a single-layer phase gradient metasurface lens is presented to achieve millimeter-wave focusing at a focal point of 13 mm regardless of the incident angle. The proposed metasurface lens is fabricated by constructing subwavelength-thick (< λ/10) phase elements composed of two metallic ...
At this critical point, which lies exactly at the localization transition, when the phase gradient φ is varied, a Floquet version of the Harper–Hofstadter butterfly emerges for the quasienergy spectrum(Fig. 3b). Fig. 2: Experimental implementation of one-dimensional quasicrystals via photonic ...

New examples and sources of ghost peaks in reversed-phase gradient HPLC are described and related to previous publications to give a broad perspective of ghost peak problems. In one new example the ghost peak was found to be due to mixing problems caused by a period of non-delivery of the ...

Optimal regularity estimates are established for the gradient of solutions to non-uniformly elliptic equations of Orlicz double phase with variable exponents type in divergence form under sharp conditions on such highly nonlinear operators for the Calderón–Zygmund theory.Access...
By doing this, the LCP component will automatically gain an equal and opposite phase gradient, and thus be deflected at an angle of \(-\alpha\) towards to Y-direction due to the conjugation phase functions of PB phase. In absence of propagation phase, the co-polarized light will remain ...
(i.e., the array period) should satisfy:Px,y<λSPP/2, whereλSPPis the wavelength of the corresponding surface plasmon polariton mode30. At the same time, the unit cell period should be large enough to allow for variation of the nanobrick widths (resulting in the phase gradient response)...
