Tuneable Capacitor based on dual picks profile of the sacrificial layer
In this paper, we present a novel dual gap tuneable capacitor process based
on the profile of the sacrificial layer. This profile involves a tri-layer
photo-resist process with only one mask level. This realization is based on a
special profile of the sacrificial layer designed by two picks. The mechanism
of the sacrificial layer realisation is dependent on resist thickness, resist
formulation (viscosity, type of polymer and/or solvent, additives...), design
of the patterned layer (size or width) and the conditions under which this
layer is prepared: thermal treatment, etch back processes... In this
communication we demonstrate influence of the later parameters and discuss how
a dual pick profile was achieved.Comment: Submitted on behalf of EDA Publishing Association

The valuation of clean spread options: linking electricity, emissions and fuels
The purpose of the paper is to present a new pricing method for clean spread options, and to illustrate its main features on a set of numerical examples produced by a dedicated computer code. The novelty of the approach is embedded in the use of a structural model as opposed to reduced-form models which fail to capture properly the fundamental dependencies between the economic factors entering the production process
Shadowing in Inelastic Scattering of Muons on Carbon, Calcium and Lead at Low XBj
Nuclear shadowing is observed in the per-nucleon cross-sections of positive
muons on carbon, calcium and lead as compared to deuterium. The data were taken
by Fermilab experiment E665 using inelastically scattered muons of mean
incident momentum 470 GeV/c. Cross-section ratios are presented in the
kinematic region 0.0001 < XBj <0.56 and 0.1 < Q**2 < 80 GeVc. The data are
consistent with no significant nu or Q**2 dependence at fixed XBj. As XBj
decreases, the size of the shadowing effect, as well as its A dependence, are
found to approach the corresponding measurements in photoproduction.Comment: 22 pages, incl. 6 figures, to be published in Z. Phys.

Observation of band gaps in the gigahertz range and deaf bands in a hypersonic aluminum nitride phononic crystal slab
International audienceWe report on the observation of elastic waves propagating in a two-dimensional phononic crystal composed of air holes drilled in an aluminum nitride membrane. The theoretical band structure indicates the existence of an acoustic band gap centered around 800 MHz with a relative bandwidth of 6.5% that is confirmed by gigahertz optical images of the surface displacement. Further electrical measurements and computation of the transmission reveal a much wider attenuation band that is explained by the deaf character of certain bands resulting from the orthogonality of their polarization with that of the source
