  • Briest, Niklas; Garbe, Heyno; Potthast, S. (Göttingen : Copernicus GmbH, 2016)
    This paper discusses a field measurement method, based on a two-antenna setup, to qualify the transmission of transient signals inside a GTEM cell. The transmission characteristic of the GTEM1250 is evaluated by the Pearson ...
  • Wittel, H.; Affeldt, C.; Bisht, A.; Doravari, S.; Grote, H.; Lough, J.; Lück, H.; Schreiber, E.; Strain, K.A.; Danzmann, Karsten (Washington, DC : Optical Society of America, 2018)
    Large scale laser interferometric gravitational wave detectors (GWDs), such as GEO 600 require high quality optics to reach their design sensitivity. The inevitable surface imperfections, inhomogeneities, and light-absorption ...
  • Ahrens, Andreas; Sandmann, Andre; Bremer, Kort; Roth, Bernhard; Lochmann, Steffen (Bellingham, WA : S P I E - International Society for Optical Engineering, 2015)
    In this paper multiple-input multiple-output (MIMO) signal processing is investigated for fibre optic sensor applications. A (2 × 2) MIMO implementation is realized by using lower-order and higher-order mode groups of a ...
