Multiple wavefront manipulation through matrix algebra

Applied Physics B, 2021
A technique for manipulating wavefronts of propagated objects is proposed, applying matrix algebra to data containing the amplitude and phase information of objects previously propagated. Matrices act as operators, altering the initial conditions of the propagated objects, such as their spatial coordinates, reflection effects, and changes in depth.

Transmission and reflection mode switching terahertz metasurface for wavefront manipulation

International Conference on Laser, Optics and Optoelectronic Technology, 2023
Metasurfaces possess the ability to manipulate the wavefront of electromagnetic waves, but the majority of them are limited to single transmission or reflection mode without altering their structure.

Compensating Plasmonic Losses by Wavefront Manipulation

Frontiers in Optics 2015, 2015
We demonstrate experimentally the generation of unique surface-plasmon beams, which compensate the inherent losses of plasmons without using gain media, and show that these beams can extend the limited propagation length of surface-plasmons.

Independent wavefront manipulation of broadband spin-decoupled metasurfaces based on equivalent circuit model

Physica Scripta, 2023
Various functional meta-devices have exhibited powerful manipulation of orbital angular momentum spectrums, but they are still faced with the issue of inherent spin-correlated characteristic and lack of effective method to design metasurface.

Bi-Isotropic Huygens’ Metasurface for Polarization-Insensitive Cross-Polarization Conversion and Wavefront Manipulation

IEEE Transactions on Antennas and Propagation
A bi-isotropic Huygens’ metasurface (BIHMS) is proposed for polarization-insensitive cross-polarization conversion and wavefront manipulation, which can transmit and twist a linearly polarized (LP) incident wave with arbitrary azimuth to its cross ...

A Chiral Metasurface for Vortex Wavefront Manipulation in Microwave Region

IEEE International Workshop on Electromagnetics: Applications and Student Innovation Competition, 2023
Phase-engineered metasurfaces are widely used for wavefront reconstruction, as they can introduce a specific spatial phase distribution function. However, the most commonly used phase modulation method, geometric phase, can only regulate circular ...
