    • An audio watermarking algorithm via zero assigned filter banks 

      Yücel, Zeynep; Özgüler, A. Bülent (IEEE, 2005)
      In order to identify the owner and distributor of digital data, a watermarking scheme for audio files is proposed in frequency domain. The scheme satisfies the imperceptibility and persistence requirements and is robust ...
    • Practical multi-featured perfect absorber utilizing high conductivity silicon 

      Gok, A.; Yilmaz, M.; Bıyıklı, N.; Topallı, K.; Okyay, Ali Kemal (Institute of Physics Publishing, 2016)
      We designed all-silicon, multi-featured band-selective perfect absorbing surfaces based on CMOS compatible processes. The center wavelength of the band-selective absorber can be varied between 2 and 22 μm while a bandwidth ...
