Plasmonic trapping with realistic dipole nanoantennas: Analysis of the detection limit

Olivier Martin, Andrea Lovera

We use numerical simulations based on the surface integral technique to study the detection limit of plasmonic trapping with realistic dipole antennas. The induced plasmon resonance shift due to the coupling between an antenna and a nanoparticle is studied ...

Recent developments on reconfigurable band-filtering antennas

Julien Perruisseau-Carrier

This paper presents implementations of very wideband antennas with reconfigurable band-rejection filtering within the band. The base antenna topology used is a dipole slot bow-tie whose maximal dimension at the lowest matched frequency is only 0.2λ0. The a ...

Integer-Forcing Linear Receivers: A New Low-Complexity MIMO Architecture

Michael Christoph Gastpar

We propose a new framework for MIMO decoding based on a recently developed technique for reliably conveying linear equations over wireless channels. Each transmit antenna sends an independent data stream using the same linear code. As a result, any integer ...
