Rational design and optimization of plasmonic nanoarrays for surface enhanced infrared spectroscopy

Hatice Altug, Shyamsunder Erramilli

We present an approach for rational design and optimization of plasmonic arrays for ultrasensitive surface enhanced infrared absorption (SEIRA) spectroscopy of specific protein analytes. Motivated by our previous work that demonstrated sub-attomole detecti ...

Nanoparticle-Based Metamaterials as Multiband Plasmonic Resonator Antennas

Hatice Altug, Arif Engin Cetin, Serap Aksu

Plasmonic metamaterials based on metal-dielectric nanostructures exhibit unique optical properties such as high near-field enhancement, negative refractive indexing, and optical cloaking. In this paper, we present a plasmonic multiband metamaterial based o ...

A bottom-up approach to fabricate optical metamaterials by self-assembled metallic nanoparticles

Toralf Scharf

We introduce a novel bottom-up approach to fabricate by self assembly a metamaterial from metallic nanoparticles in a two-step process. In the first step, a metamaterial made of densely packed silver nanoparticles is required. The material dispersion with ...

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 ...

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 ...

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 ...

Three-Dimensional Negative Index of Refraction at Optical Frequencies by Coupling Plasmonic Waveguides

We identify a route towards achieving a negative index of refraction at optical frequencies based on coupling between plasmonic waveguides that support backwards waves. We show how modal symmetry can be exploited in metal-dielectric waveguide pairs to achi ...

Acoustic transmission line metamaterial with negative/zero/positive refractive index

Juan Ramon Mosig, Hervé Lissek, Frédéric Bongard

A one-dimensional acoustic negative refractive index metamaterial based on the transmission line approach is presented. This structure implements the dual transmission line concept extensively investigated in microwave engineering. It consists of an acoust ...

We propose to model periodic structures by equivalent multiconductor transmission lines (MTLs). The developed technique is based on a multimodal representation of the periodic structure unit cell, such as required for periodically loaded MTLs and periodica ...

Metallic nanostructures show interesting optical properties due to their plasmonic resonances, and when arranged in three-dimensional (3D) arrays hold promise for optical metamaterials with negative refractive index. Towards this goal a simple, cheap, and ...
