Noninterleaved Completely Helicity-Modulated Cascaded Metasurface Empowering Full-Space Energy-Controllable Arbitrary Wavefront Manipulation

IEEE Transactions on Antennas and Propagation
Multidimensional regulation of electromagnetic (EM) waves, especially for that joint amplitude-phase modulation occurring at different polarization channels, is pivotal for new-generation information processing and wireless communication.

A transformation elasticity based device for wavefront manipulation

NDT & E International, 2019
Abstract The authors propose a metamaterial plate made of gradient refractive index phononic crystals for manipulation of the wavefront of propagating elastic waves in solid media. A square unit cell with through holes is considered as the basis for the proposed metematerial.

Binary wavefront manipulation using an epi-detected SHG guidestar

BiOS
Multiphoton microscopy applied in bone tissue is susceptible to optical aberrations caused by heterogeneity in refractive index. Optical clearing can be applied to alleviate some of these aberrations, but it is invasive and causes deviations from normal ...

Wavefront Manipulation of Harmonic Generations via Nonlinear Metasurface

Conference on Lasers and Electro-Optics, 2016
We present a nonlinear metasurface for harmonic light generation and manipulation. The beam steering functions of harmonic generations is demonstrated with frequency up to UV range, which can be further increased using high harmonic generations.

Broadband manipulation of acoustic wavefronts by pentamode metasurface

Applied Physics Letters, 2015
An acoustic metasurface with a sub-wavelength thickness can manipulate acoustic wavefronts freely by the introduction of abrupt phase variation. However, the existence of a narrow bandwidth and a low transmittance limits further applications. Here, we present a broadband and highly transparent acoustic metasurface based on a frequency-independent ...

Factors Affecting Visual Performance after Customized Wavefront Manipulation

Frontiers in Optics 2011/Laser Science XXVII, 2011
Abstract (35 Word Limit) The success of customized vision correction depends on the relative significance of the higher order aberration of the eye, the feasibility of implementing the correction methods and the neural system’s capability to benefit fully from improved optics.
