France's strict brand of secularism has deep historical roots - but some want to soften it, says the BBC's Henri Astier.

In this paper we experimentally realize high-order photonic topological insulator as a two-dimensional triangular distorted Kagome lattice that supports two types of topological states: 1D topological ...

The Infineon AIROC-Wi-Fi-Bluetooth-STM32 Expansion Pack is an extension of the CMSIS-Pack standard established by Arm to support Wi-Fi and BLE application on STM32 MCUs with Infineon Wireless Combo ...

We report on numerical and experimental results on macro bending losses in single-cell Kagome-lattice hollow-core photonic crystal fibers. Fibers with different cladding layer numbers have been ...
