    • Inverse scattering of dispersive stratified structures 

      Skaar, Johannes; Haakestad, Magnus Willum (2012)
      We consider the inverse-scattering problem of retrieving the structural parameters of a stratified medium consisting of dispersive materials, given knowledge of the complex reflection coefficient in a finite frequency ...

    • Reciprocity and the scattering matrix of waveguide modes 

      Svendsen, Guro Kristin; Haakestad, Magnus Willum; Skaar, Johannes (2013)
      The implications of the Lorentz reciprocity theorem for a scatterer connected to waveguides with arbitrary modes, including degenerate, evanescent, and complex modes, are discussed. In general it turns out that a matrix ...
