    • Causality, 'superluminality', and reshaping in undersized waveguides 

      Sokolovski D.; Akhmatskaya E. (ECCOMAS 2012 - European Congress on Computational Methods in Applied Sciences and Engineering, e-Book Full Papers, 2012-12-31)
      We analyse the reshaping mechanism leading to apparently 'superluminal' advancement of a pulse traversing an undersized section of a waveguide. For frequencies below the first inelastic threshold (cut off one), there are ...
    • 'Superluminal paradox' in wave packet propagation and its quantum mechanical resolution 

      Sokolovski D.; Akhmatskaya E. (Annals of Physics, 2013-12-31)
      We analyse in detail the reshaping mechanism leading to apparently 'superluminal' advancement of a wave packet traversing a classically forbidden region. In the coordinate representation, a barrier is shown to act as an ...
