Ionic Transport and Charge Distribution in Miniaturized Electrochemical Energy Storage Devices by Modeling Investigation

Yannick Dufil, Frederic Favier, Thierry Brousse, Christophe Lethien, Jean Le Bideau, Olivier Fontaine

Ions are at the core of the mechanism involved in electrochemical energy storage. However, it remains difficult to physically measure the local ionic transport inside a working device. Limiting factors in the local transport in miniaturized electrochemical energy storage (MEES), especially in 3D Li…

Innovative millimetre‐wave resonators based on slow‐wave coplanar stripline components

Abdelhalim Saadi, Marc Margalef‐rovira, Youcef Amara, Loïc Vincent, Sylvie Lepilliet, Christophe Gaquière, Philippe Ferrari

In this paper, the slow-wave coplanar stripline (S-CPS) technology is utilised to design high performance and small footprint resonators operating within the millimetre-wave band from 50 to 80 GHz. The proposed resonators are designed based on high quality factor quasi-lumped capacitances and…
