    • Effective preconditioners for large integral-equation problems 

      Malas, Tahir; Ergül, Özgür; Gürel, Levent (IET, 2007-11)
      We consider effective preconditioning schemes for the iterative solution of integral-equation methods. For parallel implementations, the sparse approximate inverse or the iterative solution of the near-field system enables ...
    • Hyperbolic metamaterials based on quantum-dot plasmon resonator nanocomposites 

      Zhokovsky, S. V.; Ozel, T.; Mutlugun, E.; Gaponik, N.; Eychmuller, A.; Lavrinenko, A. V.; Demir, Hilmi Volkan; Gaponenko, S. V. (Optical Society of America, 2014)
      We theoretically demonstrate that nanocomposites made of colloidal semiconductor quantum dot monolayers placed between metal nanoparticle monolayers can function as multilayer hyperbolic metamaterials. Depending on the ...
    • Near-field light localization using subwavelength apertures incorporated with metamaterials 

      Ates, D.; Cakmak, A. O.; Özbay, Ekmel (Elsevier, 2012-03-12)
      We report strong near-field electromagnetic localization by using subwavelength apertures and metamaterials that operate at microwave frequencies. We designed split ring resonators with distinct configurations in order to ...
