0.2-<i>μ</i>m InP/GaAsSb DHBT Transferred on Si-HR With 28 mW/<i>μ</i>m² at 94 GHz

Abdelmalek Zemour, Malek Zegaoui, Christophe Coinon, Yannick Roelens, Etienne Okada, Pascal Chevalier, Mohammed Zaknoune

We present 94 GHz large-signal load-pull measurements of a transferred InP/GaAsSb double heterojunction bipolar transistor fabricated on a high-resistivity silicon (Si-HR) substrate. The characterized device features an emitter area of 0.19 × 8.9 µm 2 . Biased for highest power, an output power of…

Performance Evaluation of Cell-Free Massive MIMO Systems Based on Mixed Indoor/Outdoor Measurements

Eric Pierre Simon, Joumana Farah, Valentin Picquet, Pierre Laly

This paper presents an extensive investigation into the performance of cell-free massive multiple-input multiple-output (CF-mMIMO) systems using empirical channel data. We first detail an original measurement campaign conducted in a mixed indoor/outdoor campus environment, providing a realistic…

Low-loss, 1-m long length, silica based hollow-core THz waveguide operating at 1 THz

Georges Humbert, Jean-Louis Auguste, Guillaume Ducournau, Jean-Francois Lampin

A hollow-core THz waveguide composed of silica capillaries is proposed for low-loss THz wave propagation. Silica, despite its large absorption coefficient at THz frequencies, offers numerous fabrication advantages for developing THz waveguides. A numerical study on the anti-resonant guiding…

The Role of Absolute Space in Newton's Physics

Raffaele Pisano, Paolo Bussotti

In this paper, we examine Newton’s concept of absolute space. We aim at clarifying: (1) the reasons that led Newton to introduce this notion; (2) the arguments he used to justify its existence; (3) the relationship between absolute space and the principle of inertia; and (4) the role of absolute…
