Ultra-Compact Ka-band Metamaterial Waveguide Filters, Fabricated by Lost-Wax Casting

Romain Christophe Rémy Fleury, Maliheh Khatibi Moghaddam

This paper proposes a novel technique for the design of miniaturized Ka-band filters based on locally resonant metamaterials (LRMs), which are fabricated monolithically using lost wax casting. We implement ultra-small metamaterial filters by exploiting a n ...

Self-tracking Solar Concentration

Volker Günter Zagolla

Solar concentration is intended to decrease the cost of expensive solar cell material by replacing the solar cell with a focusing optical system as the initial receiving aperture. This reduces the amount of solar cell material needed but adds the need of t ...

Tuneable PTC effect in polymer-wax-carbon composite resistors

Thomas Maeder, Peter Ryser, Caroline Marguerite Jacq, Ludivine Ammon

Purpose: The resistivity dependence on temperature of composite resistors made of carbon fillers dispersed in an organic matrix are known to be strongly affected by the matrix thermal expansion. High positive temperature coefficient (PTC) effects, i.e. ess ...

What impacts skin color in digital photos?

Stefan Winkler, Albrecht Johannes Lindner

Skin colors are important for a broad range of imaging applications to assure quality and naturalness. We discuss the impact of various metadata on skin colors in images, i.e. how does the presence of a metadata attribute influence the expected skin color ...

Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) feedstock development and optimization for thermoplastic forming of thin planar and tubular oxygen separation membranes

Stefan Diethelm

This paper presents the processing steps for producing thin planar and tubular oxygen separation membranes by thermoplastic forming of Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) with polystyrene (PS) and stearic acid (SA) as binder. The influence of powder conten ...

Integration column: Artificial ECM: expanding the cell biology toolbox in 3D

Matthias Lütolf

Many crucial cellular processes in our tissues are governed by complex, spatio-temporally regulated interactions between cells and their extracellular matrix (ECM). These interactions can be studied using well-established 3D in vitro model systems such as ...
