DSpace is a digital service that collects, preserves, and distributes digital material. Repositories are important tools for preserving an organization's legacy; they facilitate digital preservation and scholarly communication.

  • Spectrum-aware and energy-adaptive reliable transport for internet of sensing things 

    Biçen, A. Ozan; Ergül, Özgür; Akan, Özgür B. (IEEE-Inst Electrical Electronics Engineers Inc, 2018-03)
    Wireless sensors equipped with cognitive radio, i.e., cognitive radio sensor networks (CRSN), can access the spectrum in an opportunistic manner and coexist with licensed users to mitigate the crowded spectrum problem and ...
  • Modeling of an interface between isorefractive media by a resistive surface 

    Başdemir, Hüsnü Deniz (Optical Soc Amer, 2018-02-20)
    In this study, the scattering of plane waves by a half-plane with different face impedances, which lie between isorefractive media, is analyzed. A new approach for the solution of this scenario is proposed. According to ...
  • Mode coupling in vortex beams 

    Eyyuboğlu, Halil T. (Elsevier Science Ltd, 2018-05)
    We examine the mode coupling in vortex beams. Mode coupling also known as the crosstalk takes place due to turbulent characteristics of the atmospheric communication medium. This way, the transmitted intrinsic mode of the ...
  • Diffraction of Cylindrical Waves by a Transmissive Half-Plane 

    Umul, Yusuf Ziya (Asme, 2017-10)
    The scattered acoustic waves by a transmissive half-plane, which is illuminated by a line source, are investigated. The high-frequency diffracted wave expressions are obtained by taking into account a resistive half-screen ...
  • Wave diffraction by a reflectionless half-plane 

    Umul, Yusuf Ziya (Optical Soc Amer, 2017-11-20)
    The concept of reflectionless surface is put forth, and its reflection and transmission coefficients are determined by using the scattered geometrical optics fields of transmissive and perfectly electric conducting surfaces. ...
