Subwavelength robust waveguiding with chiral metamaterial waveguides

Romain Christophe Rémy Fleury, Bakhtiyar Orazbayev, Nadège Sihame Kaïna

In this work, we design and experimentally demonstrate in the microwave range a robust metamaterial waveguide, which is formed at the boundary between two locally resonant chiral metamaterials with opposite chirality. We show that the interface states at s ...

Templating colloidal sieves for tuning nanotube surface interactions and optical sensor responses

Ardemis Anoush Boghossian, Daniel Jerôme Siefman, Alice Judith Gillen, Shang-Jung Wu, Benjamin Paul Johanès Gabriel Lambert

Surfactants offer a tunable approach for modulating the exposed surface area of a nanoparticle. They further present a scalable and cost-effective means for suspending single-walled carbon nanotubes (SWCNTs), which have demonstrated practical use as fluore ...

Permeability and capillary effects in a channel-wise non-crimp fabric

Véronique Michaud, Baris Çaglar, Helena Luisa Teixido Pedarros, Damiano Salvatori

Flow properties are investigated for a non-crimp glass fabric with large meso-channels designed for high-permeability, as compared to glass twill woven fabric. Saturated and unsaturated permeability are measured through in-plane, unidirectional, constant-p ...

Strategies for faster impregnation in melt thermoplastic resin transfer molding process

Damiano Salvatori

Continuous fiber thermoplastic composites are potential substitutes of steel in structural automotive components, since they combine fiber strength and rigidity with ductility, potential recyclability and low density of the thermoplastic (TP) matrix. Resin ...

In-plane permeability distribution mapping of isotropic mats using flow front detection

Véronique Michaud, Baris Çaglar, Damiano Salvatori

In-plane permeability of textile fabrics is often characterized by one-dimensional rectilinear flow experiments, displaying limitations related to potential race-tracking effects and the need to run experiments at several fiber volume fractions. We propose ...

Transport characteristics of saturated gas diffusion layers treated with hydrophobic coatings

Sophia Haussener, Seyedmohamad Moosavi, Mathias Raphaël Niffeler

Water flooding of cathodic gas diffusion layers (GDLs) in proton-exchange membrane fuel cells at high current densities or low temperatures limits efficient operation due to disturbed transport of reactants to the catalytic sites or products away into the ...

Evaluation of the instantaneous profile method for the determination of the relative permeability function

Anne-Catherine Adolphine M Dieudonné

Experimental determination of water permeability in unsaturated conditions is a critical issue. Among the existing experimental techniques, the instantaneous profile method is frequently used. When applied to bentonite-based materials, the method often sho ...

Permeability of textile fabrics with spherical inclusions

Véronique Michaud, Baris Çaglar

We investigated the effect of rigid spherical inclusions such as microcapsules and fillers on the permeability of fabrics by using glass beads as model inclusions. Beads with a range of diameters (40-800 mu m) and volume fractions (2.5-10%) were sieved bet ...

Numerical Approximation of Flows in Random Porous Media

Francesco Tesei

The objective of this thesis is to develop efficient numerical schemes to successfully tackle problems arising from the study of groundwater flows in a porous saturated medium; we deal therefore with partial differential equations(PDE) having random coeffi ...

Theory, design and measurement of near-optimal graphene reconfigurable and non-reciprocal devices at terahertz frequencies

Michele Tamagnone

This thesis explores the applications of graphene for terahertz and far infrared optical components and antennas, with particular emphasis on tunable and non-reciprocal devices. Both terahertz technologies and graphene are emerging fields which hold many p ...
