Electromagnetic modes of a disordered photonic crystal

Vincenzo Savona

We present a systematic numerical approach to compute the eigenmodes and the related eigenfrequencies of a disordered photonic crystal, characterized by small fluctuations of the otherwise periodic dielectric profile. The field eigenmodes are expanded on t ...

Active tensegrity structures with sliding cables - static and dynamic behaviour

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali

Tensegrities are spatial, reticulated and lightweight structures that are increasingly investigated as structural solutions for active and deployable structures. Tensegrity systems are composed only of axially loaded elements providing opportunities for ac ...

Moving horizon estimation for distributed nonlinear systems with application to cascade river reaches

Giancarlo Ferrari Trecate, Marcello Farina

In this paper we consider a nonlinear constrained system observed by a sensor network and propose a distributed state estimation scheme based on moving horizon estimation (MHE). In order to embrace the case where the whole system state cannot be reconstruc ...

Laser-pumped double-resonance atomic clock using a micro-fabricated Rb cell

Nico de Rooij, Yves Pétremand

We present first results on a laser-pumped, double resonance (DR) Rubidium atomic clock, based on microfabricated Rb vapour cells. The study aims towards a miniature atomic clock [1] based on DR, using a lowpower laser as pump light source and a miniaturiz ...
