Electromagnetic Forces and Torques: From Dielectrophoresis to Optical Tweezers

Electromagnetic forces and torques enable many key technologies, including optical tweezers or dielectrophoresis. Interestingly, both techniques rely on the same physical process: the interaction of an oscillating electric field with a particle of matter. ...

Controlling surface effects in extremely high aspect ratio gold plasmonic electrodes

Olivier Martin, Christian Santschi, Marco Riccardi

Nanofabrication is key to many technological advances, especially the challenge of merging nanophotonics with electronics. Here, we investigate the fabrication process of plasmonic interdigitated gold electrodes having a very high aspect ratio (i.e. long a ...

Multipolar expansions for scattering and optical force calculations beyond the long wavelength approximation

Olivier Martin, Karim Achouri, Andrei Kiselev, Marco Riccardi

We review three different approaches for the calculation of electromagnetic multipoles, namely, the Cartesian primitive multipoles, the Cartesian irreducible multipoles, and the spherical multipoles. We identify the latter as the best suited to describe th ...

Low and high frequency electromagnetic forces: numerical modelling and practical applications

Marco Riccardi

The understanding and manipulation of nanoscale analytes is a central theme in nanotechnology and has been one of the main driving forces behind the development of this field as we know it today. Furthermore, such a technology has the potential to also rev ...

An Experimental Study Of The Photoresponse Of 1T-1R Oscillators Based On Vanadium Dioxide: Towards Spiking Sensing Systems

Olivier Martin, Mihai Adrian Ionescu, Teodor Rosca, Marco Riccardi, Fatemeh Qaderi Rahaqi

In this work we investigate the effect of visible light radiation on compact 1T-1R relaxation spiking oscillator cells based on 2-terminal Vanadium dioxide (VO2) structures. We illuminate the devices using a tunable wavelength laser between 400 and 850 nm ...

Role of electric currents in the Fano resonances of connected plasmonic structures

Olivier Martin, Marco Riccardi

In this work, we use finite elements simulations to study the far field properties of two plasmonic structures, namely a dipole antenna and a cylinder dimer, connected to a pair of nanorods. We show that electrical, rather than near field, coupling between ...
