Propagation in bianisotropic media - reflection and transmission

In this paper a systematic analysis that solves the wave propagation problem in a general bianisotropic, stratified media is presented. The method utilizes the concept of propagators, and the representation of these operators is simpli- fied by introducing the Cayley-Hamilton theorem. The propagators propagate the total tangential electric and magnetic fields in the slab and only outside the slab

New Hopes for Democracy or a Pirated Elite? Swedish Social Media Users and Political Mobilisation.

In this study, a group of Swedish social media users – politically active as well as “unpolitical” users – are interviewed in focus groups as well as individually about their attitudes towards online political participation, providing a deeper, more informed view of how social media participation works. Sweden, with its high levels of voluntary participation and with an avant-garde position in Int

On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings

Popular Abstract in Swedish Den rykande startpistolen eller Konsten att ta tid på en flygande elektron Flygande elektroner kan berätta mycket om hur världen sitter ihop. Elektroner som lämnar ytan av något material avslöjar både vilka atomer som finns i materialet och hur de kemiska bindingarna ser ut. Allt detta är nödvändigt att förstå när man vill utveckla nya material – till exempel för kretTime-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution. However, the advent of angle-resolved TOF spectrometers for electron energy analysis cha
