Planar Photonics with Metasurfaces [PDF]

open access: yesScience, 2013
Background Metamaterials (MMs) are smartly engineered structures with rationally designed, nanostructured building blocks that allow us to build devices with distinct responses to light, acoustic waves, and heat flows that are not attainable with naturally available materials. Advances

A Metasurface Superstrate for Mutual Coupling Reduction of Large Antenna Arrays

open access: yesIEEE Access, 2020
In this paper, a ε-negative metasurface superstrate is proposed for mutual coupling reduction of large antenna arrays. Unlike the previous decoupling metasurface works that are mostly confined to two-ports antennas, the proposed decoupling ...

Do bilayer metasurfaces behave as a stack of decoupled single-layer metasurfaces? [PDF]

open access: yesarXiv, 2023
Flat optics or metasurfaces have opened new frontiers in wavefront shaping and its applications. Polarization optics is one prominent area which has greatly benefited from the shape-birefringence of metasurfaces. However, flat optics comprising a single layer of meta-atoms can only perform a subset of polarization transformations, constrained by a ...

Hybrid plasmonic metasurfaces [PDF]

open access: yesJournal of Applied Physics, 2019
Plasmonic metasurfaces based on ensembles of distributed metallic nanostructures can absorb, scatter, and in other ways shape light at the nanoscale. Forming hybrid plasmonic metasurfaces by combination with other materials opens up for new research directions and novel applications.

Ultrathin Gold for Robust Multi‐Element Surface Plasmon Resonance Biosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
This is a pioneering work where for the first time we applied recently synthesised ultrathin layer of gold for plasmonic biosensing that makes use of multi‐element architectures. This study solves the problem of stability of the multi‐element biosensors as well as demonstrates increased sensitivity achieved by utilising new additions to low‐dimension ...

Theoretical study on dynamical planar-chirality switching in checkerboard-like metasurfaces

open access: yesEPJ Applied Metamaterials, 2017
In this paper, we show that the handedness of a planar chiral checkerboard-like metasurface can be dynamically switched by modulating the local sheet impedance of the metasurface structure.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.
