  • Add-Drop and Channel-Drop Optical Filters Based on Photonic Crystal Ring Resonators 

    Tavousi, A.؛ Mansouri-Birjandi, M. A.؛ Saffari, M. (University of Sistan and Baluchestan, 2012-12-01)
    Here, we propose an add-drop and a channel drop filter based on two-dimensional photonic crystal all circular ring resonators. These structures are made of a square lattice of silicon rods with the refractive index n1=3.464 ...

  • A Novel Small E–Ring Shaped Monopole Antenna with Dual Band-Notch Function for UWB Wireless Communications 

    Ojaroudi, N.؛ Ojaroudi, M.؛ Amiri, S. (University of Sistan and Baluchestan, 2012-12-01)
    This paper presents an E-ring shaped printed monopole antenna for UWB applications with dual notched bands performance. In order to generate single frequency band notch function, we applied a U-ring shaped monopole antenna, ...

  • Users as the Biggest Threats to Security of Health Information Systems 

    Bakhtiyari-Shahri, A.؛ Ismail, Z. (University of Sistan and Baluchestan, 2012-12-01)
    There are a lot of researches in the world about attacks on information systems (IS). Although there have been many attempts to classify threats of IS's especially in Health Information Systems (HIS), it is still necessary ...
