Feeding structure influence on performance of two UWB antennas near a human arm

Anja Skrivervik, Mohsen Koohestani

This paper reports a study of the feeding structure influence on impedance matching and system fidelity factor of two loaded UWB antennas when placed near a human arm. To this aim, two identical dielectric loaded versions of the same UWB antenna designs wi ...

Learning Object-level Impedance Control for Robust Grasping and Dexterous Manipulation

Aude Billard, Hang Yin, Miao Li, Kenji Tahara

Object-level impedance control is of great importance for object-centric tasks, such as robust grasping and dexterous manipulation. Despite the recent progress on this topic, how to specify the desired object impedance for a given task remains an open issu ...

Study of bending reliability and electrical properties of platinum lines on flexible polyimide substrates

Nico de Rooij, Danick Briand, Jérôme Courbat, Francisco Molina Lopez

We have experimentally studied the variation in electrical resistance of flexible platinum lines patterned on polyimide foil when they are subjected to circular bending constraints. The lines were patterned by means of standard photolithography and sputter ...

Multi-Band Outphasing Power Amplifier Design for Mobile and Base Stations

Omid Talebi Amiri

New generations of wireless communication systems require linear efficient RF power amplifiers (PAs) for higher transmission data rates and longer battery life. On the contrary, conventional PAs are normally designed for peak efficiency under maximum outpu ...

Electroacoustic absorbers for the low-frequency modal equalization of a room: what is the optimal target impedance for maximum modal damping, depending on the total area of absorbers?

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar, Véronique Adam

Electroacoustic absorbers consist of loudspeakers, shunted with an electrical circuit designed to obtain a given acoustic impedance. Their design and principles are now well understood. Unidimensional experiments, using plane waves under normal incidence i ...

Metamaterial buffer for broadband non-resonant impedance matching of obliquely incident acoustic waves

Romain Christophe Rémy Fleury

Broadband impedance matching and zero reflection of acoustic waves at a planar interface between two natural materials is a rare phenomenon, unlike its optical counterpart, frequently observed for polarized light incident at the Brewster angle. In this art ...
