How Multiple Streams Influence Agenda‐Setting for Water Reuse in Swiss Substates
Environmental Policy and Governance, EarlyView.ABSTRACT As climate change creates significant challenges for both the environment and society, potential mitigation and adaptation solutions are widely discussed. Yet, neither challenges nor their potential solutions automatically reach the political agenda or lead to a policy decision.

, 2010 This paper studies the possibility of using axicons in Free Space Optics (FSO) systems. The behavior of the pseudo- Bessel beams generated by "logarithmic" and "linear" axicons, with or without stops, was analyzed through the Huygens-Fresnel integral of diffraction in cylindrical coordinates.

FSO Detection using differential signaling in outdoor correlated-channels condition [PDF]
, 2016 In this letter, we introduce a detection technique based on differential signaling scheme for outdoor free space optical communications. This method requires no channel state information (CSI) and does not suffer from the computational load compared with

Laser &Photonics Reviews, EarlyView.A dual‐layer metasurface is integrated on a fiber‐array facet to realize compact, plug‐and‐play free‐space optical links with cylindrical vector beam (CVB) space‐division multiplexing. An optimized off‐axis collimation layer steers multiple channels, while a Dammann vortex layer performs polarization–topology conversion for bidirectional CVB (de ...

RF/FSO and THz/FSO Relaying Systems
This chapter delves into the potential of relay-assisted transmission to alleviate fading in free-space optical (FSO) systems. We focus on evaluating the efficacy of a dual-hop relay system for RF (millimeter-wave and terahertz)/FSO (RF/FSO) communications in the presence of pointing errors.

Routing and Downlink Resource Allocation for Multicast Traffic in LEO Satellite Constellations
International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT In this work, we optimize unicast and multicast traffic delivery over non‐terrestrial networks (NTNs) to users on the ground through direct satellite downlink (DL). We consider a gateway‐free mesh architecture with low Earth orbit (LEO) satellites interconnected via inter‐satellite links (ISLs), where unicast and multicast services compete for
