What can metamaterials be used for?

Potential applications of metamaterials are diverse and include optical filters, medical devices, remote aerospace applications, sensor detection and infrastructure monitoring, smart solar power management, crowd control, radomes, high-frequency battlefield communication and lenses for high-gain antennas, improving …

What are plasmonic Metasurfaces?

So-called plasmonic metasurfaces are 2D arrays of such optical nanoantennas, distributed on a substrate to provide properties beyond the mere average response of the materials they are made from.

What makes a good plasmonic material?

Plasmonic materials are metals or metal-like materials that exhibit negative real permittivity. Most common plasmonic materials are gold and silver. However, many other materials show metal-like optical properties in specific wavelength ranges.

What are the major properties of metamaterials?

Properties of metamaterials

• Invisibility. Due to their peculiar optical capabilities (wavelength shorter than visible light), metamaterials can be invisible.
• Acoustic control.
• Negative electrical permittivity and magnetic permeability.

What is surface lattice resonance?

Surface lattice resonances appear in periodic plasmonic nanoparticle arrays due to the hybridization of plasmonic and photonic modes. Compared to localized surface plasmon resonances of single particles, these coupled modes feature reduced linewidth, angle-dependent dispersion, and long-range collectivity.

What are plasmonic nanoparticles used for?

Plasmonic nanoparticles are extremely strong absorbers and scatters of light and are used in lateral flow diagnostics, surface enhanced spectroscopy, labeling, and color changing sensors.

What are examples of metamaterials?

Some examples of available metamaterials are negative index metamaterials, chiral metamaterials, plasmonic metamaterials, photonic metamaterials, etc.

What are metamaterials PDF?

Since a metamaterial is a material which is having negative permittivity and permeability, it can be regarded as an artificial medium with negative index of refraction. Negative refraction was determined by a Snell’s Law.

What are metamaterials and how do they work?

Metamaterials are artificially engineered materials designed to induce customized properties in a material that originally does not exist. The metamaterial structures are obtained by making significant changes in internal material structure through different techniques.

What is surface lattice?

What is plasmonic system?

Plasmonic nanoparticles are particles whose electron density can couple with electromagnetic radiation of wavelengths that are far larger than the particle due to the nature of the dielectric-metal interface between the medium and the particles: unlike in a pure metal where there is a maximum limit on what size …

What is plasmonic absorption?

Plasmonic metal nanoparticles – including gold, silver, and platinum – are highly efficient at absorbing and scattering light. By changing nanoparticle size, shape, and composition, the optical response can be tuned from the ultraviolet through the visible to the near-infrared regions of the electromagnetic spectrum.
