Graphene Antennas: Can Integration and Reconfigurability Compensate for the Loss?

Julien Perruisseau-Carrier, Michele Tamagnone

In this opening presentation we will first recall the main characteristics of graphene conductivity and electromagnetic wave propagation on graphene-based structures. Based on these observations and different graphene antenna simulations from microwave to ...

Omnidirectional spin-wave nanograting coupler

Dirk Grundler, Haiming Yu

Magnonics as an emerging nanotechnology offers functionalities beyond current semiconductor technology. Spin waves used in cellular nonlinear networks are expected to speed up technologically, demanding tasks such as image processing and speech recognition ...

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 ...

Ferromagnetic nanodisks for magnonic crystals and waveguides

Dirk Grundler

Spin wave excitations in dipolarly coupled nanodisks from permalloy are investigated. We address, both, onedimensional (1D) chains and two-dimensional (2D) arrays consisting of nanodisks of different diameter. An out-of-plane magnetic field allows us to in ...

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 ...

Spatial control of spin-wave modes in Ni80Fe20 antidot lattices by embedded Co nanodisks

Dirk Grundler

Combined all-electrical spin-wave and micro-focused Brillouin light scattering spectroscopies have been used to study spin-wave eigenmodes in bicomponent lattices formed by periodic Co nanodisks introduced in nanotroughs etched into a thin Ni80Fe20 film. W ...

Spin Rings in Bistable Planar Semiconductor Microcavities

Romuald Houdré, Timothy Chi Hin Liew

A remarkable feature of exciton-polaritons is the strongly spin-dependent polariton-polariton interaction, which has been predicted to result in the formation of spin rings in real space [Shelykh et al., Phys. Rev. Lett. 100, 116401 (2008)]. Here we experi ...

2010

Metamaterials (MTMs) are broadly defined as artificial composite materials specifically engineered to produce desired unusual electromagnetic properties not readily available in nature. The most interesting unusual property achievable with MTMs is probably ...
