Plasmon Induced Transparency with Asymmetric pi-Shaped Metamaterials

Hatice Altug, Arif Engin Cetin

We propose a planar metamaterial composed of asymmetrically positioned pi-shaped structures that exhibits plasmon induced transparency (PIT). The system enables fine tuning of PIT spectral behavior and near field enhancement control and provides smaller mo ...

Transmission Line Based Metamaterials for Acoustic Waves

Juan Ramon Mosig, Hervé Lissek, Frédéric Bongard

We present our recent work on a one-dimensional acoustic negative refractive index metamaterial based on the concept of dual transmission line extensively investigated in microwave engineering. The proposed structure consists of an acoustic waveguide perio ...

Passive/Active Acoustic metamaterials

Hervé Lissek

Within the last years, an increasing number of studies have been carried out in the field of acoustic metamaterials. These artificial composite materials aim at achieving new macroscopic properties, like negative refraction, that are not readily present in ...

Plasmon induced transparency in cascaded pi-shaped metamaterials

Hatice Altug, Arif Engin Cetin

We experimentally and numerically demonstrate a planar metamaterial consisting of two asymmetrically positioned pi-structures in a single unit that exhibits plasmonic analogue of electromagnetically induced transparency (EIT). Through the coupling of the c ...

Tunable metamaterial response of a Ni80Fe20 antidot lattice for spin waves

Dirk Grundler

All-electrical spin-wave spectroscopy and frequency-resolved magneto-optical Kerr-effect measurements are combined to study spin waves propagating through a magnetic antidot lattice nanopatterned from a Ni80Fe20 thin film. Spin waves are injected from a pl ...

Ab initio theory of Fano resonances in plasmonic nanostructures and metamaterials

Olivier Martin, Benjamin Gallinet

An ab initio theory for Fano resonances in plasmonic nanostructures and metamaterials is de- veloped using Feshbach formalism. It reveals the role played by the electromagnetic modes and material losses in the system, and enables the engineering of Fano re ...

Analytical description of Fano resonances in plasmonic nanostructures

Olivier Martin, Benjamin Gallinet

We report on the derivation of analytical formulas for the lineshape of Fano resonances in plasmonic nanostructures as a function of their electromagnetic response. Contrary to the original work of Fano, the formalism proposed here includes losses in the m ...

Flexible Plasmonics on Unconventional and Nonplanar Substrates

Hatice Altug, Serap Aksu, Min Huang

Flexible plasmonics and metamaterials on polymeric and nonplanar substrates are demonstrated using nanostencil lithography. High-resolution fabrication with 10 nm accuracy is achieved at high throughput and low cost in a single fabrication step. Optical tu ...

Influence of electromagnetic interactions on the lineshape of plasmonic Fano resonances

Olivier Martin, Benjamin Gallinet

The optical properties of plasmonic nanostructures supporting Fano resonances are investigated with an electromagnetic theory. Contrary to the original work of Fano, this theory includes losses in the materials composing the system. As a result, a more gen ...
