Coupling effect of split ring resonator and its mirror image

F. Zhang, Q. Zhao, J. Sun, J. Zhou, D. Lippens

We report on experimental and numerical studies on the coupling effect of a single split ring resonator (SRR) and its mirror image inside an X-band hollow waveguide. It is shown that, for single SRR with gap bearing side perpendicular to E field, the magnetic resonance exhibits red/blue shift as...

Energy-autonomous picocell remote antenna unit for radio-over-fiber system using the multiservices concept

C. Lethien, David Wake, Bernard Verbeke, Jean-Pierre Vilcot, Christophe Loyez, Malek Zegaoui, Nathan J Gomes, N. Rolland, Paul-Alain Rolland

The study reported in this letter deals with the extension of the multiservices concept to radio-over-fiber systems with energy-autonomous picocell remote antenna units. Continuous-power, radio-frequency, and digital signals have been combined in a single multimode fiber for the first time. The...

Loosening quantum confinement : observation of real conductivity caused by hole polarons in semiconductor nanocrystals smaller than the Bohr radius

Ronald Ulbricht, Joep J. H. Pijpers, Esther Groeneveld, Rolf Koole, Celso de Mello Donega, Daniel Vanmaekelbergh, Christophe Delerue, Guy Allan, Mischa Bonn

We report on the gradual evolution of the conductivity of spherical CdTe nanocrystals of increasing size from the regime of strong quantum confinement with truly discrete energy levels to the regime of weak confinement with closely spaced hole states. We use the high-frequency (terahertz) real and...

Switching properties of nano-scale multi-axial ferroelectrics : geometry and interface effects

Laurent Baudry, Igor A. Luk'Yanchuk, Anaïs Sené

We consider the nonuniform polarization switching in the electroded nanoscale cubic ferroelectric, having the nano-size cylindric shape. Assuming the weak anisotropy, that can be realized e.g. in Lead Zirconate Titanate close to morphotropic point, we show that vortex-like polarization texture can...
