• Few- and Single-Cycle Coherent Pulse Propagation in Multi-Level Media 

      Marskar, Robert (Doktoravhandlinger ved NTNU, 1503-8181; 2014:154, Doctoral thesis, 2014)
      Recent experimental realizations of single-cycle pulses in the terahertz, infrared, and optical regions provide promising light sources for applications in telecommunication, medical imaging, spectroscopy, and coherent ...
    • Multilevel Maxwell-Bloch simulations in inhomogeneously broadened media 

      Marskar, Robert; Österberg, Ulf Lennart (Journal article; Peer reviewed, 2011)
      A compact numerical method for simulating ultrafast pulse interaction with inhomogeneously broadened multi-level media is reported. We use a low-dispersion pseudospectral scheme with fourth order time stepping for Maxwell’s ...
    • Nonlinear Vibration-Rotation Modes Of Inviscid Droplets 

      Marskar, Robert (Master thesis, 2009)
    • Simulations and Measurements of Streamer discharges near Dielectrics 

      Midttun, Sigurd Gard (Master thesis, 2017)
      A novel numerical fluid model for simulating streamer discharges has been tested and utilized with a two-diemnsional triple junction configuration. The triple junction was located at the upper end of a 1 cm dielectric rod, ...
    • Streamer and surface charge dynamics in non-uniform air gaps with a dielectric barrier 

      Meyer, Hans Kristian Hygen; Marskar, Robert; Blaszczyk, Andreas; Mauseth, Frank; Pedersen, Per Atle (Journal article; Peer reviewed, 2019)
      Streamer behaviour near dielectric surfaces is an important characteristic of air-solid electrical insulation systems. Accurate predictions are important for dielectric design, but dynamic aspects such as surface charging ...
    • Streamer propagation along a profiled dielectric surface 

      Meyer, Hans Kristian Hygen; Marskar, Robert; Gjemdal, Henrik; Mauseth, Frank (Peer reviewed; Journal article, 2020)
      We investigate the propagation of positive streamers along a profiled dielectric surface in air at atmospheric pressure. Results from experiments and two-dimensional planar low-temperature plasma fluid simulations are ...
    • Streamer Propagation along Dielectric Surfaces 

      Gjemdal, Henrik (Master thesis, 2019)
      Avhandlingen undersøker hvordan streamerutbredelse langs en dielektrisk overflate påvirkes av profilen på overflaten. Et eksperimentelt oppsett er utformet for å etterligne en 2D modell som også simuleres. Simuleringsprogramvaren ...
