    • Plasmonic fractal antennas 

      López Menchón, Héctor (Universitat Politècnica de Catalunya, 2016-06)
      Bachelor thesis
      Open Access
      We study the effects of using fractal shapes on the design of nanoantennas at optical geometries.
    • Scrape Off Layer turbulence and flow velocity measurements with the Li-beam diagnostic 

      Rodriguez Serra, Jorge (Universitat Politècnica de Catalunya, 2016-09)
      Master thesis (pre-Bologna period)
      Open Access
      This work studies the behavior of the plasma in the outer part of the vessel, where the magnetic field lines are no longer closed, this part in called scrape off layer. The machine studied is the experimental fusion ...
    • Shear Alfvén wave continuum spectrum with bifurcated helical core equilibria 

      Rakha, Allah; Lauber, Philipp; Mantsinen, Mervi Johanna; Spong, Donald (2019-09-09)
      Open Access
      The radial structure of the continuum spectrum of shear Alfvén and Alfvén-acoustic waves in the beta-induced Alfvén eigenmode (BAE) frequency range is modeled for tokamak plasmas in the presence of 3D effects obtained from ...
    • Simulations of Alfvénic modes in TJ-II Stellarator 

      Rakha, Allah; Mantsinen, M. J.; López-Fraguas, A.; Castejón, F.; Pablos, J.L. de; Melnikov, A.V.; Sharapov, S. E.; Spong, D. A. (Barcelona Supercomputing Center, 2017-05-04)
      Conference report
      Open Access
      Alfvénic modes are one of the subclass of instabilities prevalent in burning plasmas due to interaction of energetic particles with background plasma. In this paper we investigate the properties of these modes with 3D ...
    • Simulations of high-enthalpy gases in an Electric Arc Heater – Study of Equilibrium vs. Non- Equilibrium assumptions and Uncertainty Quantifications of an Arc Jet 

      Jiménez Miró, José Ángel (Universitat Politècnica de Catalunya / Insitut Supérieur de l'Aéronautique et de l'Espace, 2011)
      Master thesis (pre-Bologna period)
      Restricted access - author's decision
      Space exploration has experienced exceptional advances the last years since the NASA’s Apollo missions landed man on the moon. In spite of all the discoveries and advances in computational power, the heat flux on the ...
    • White paper on the future of plasma science and technology in plastics and textiles 

      Cvelbar, Uros; Walsh, James L.; Cernák, Mirko; Labay, Cédric Pierre; Canal Arias, José María; Canal Barnils, Cristina (2019-01-01)
      Open Access
      Covenantee:   Inštitut "Jožef Stefan"
      This white paper considers the future of plasma science and technology related to the manufacturing and modifications of plastics and textiles, summarizing existing efforts and the current state‐of‐art for major topics ...
