讲座人 Prof. SadiqUllah
讲座人介绍 SadiqUllah is Associate Professor in Telecommunication Engineering Department, University of Engineering & Technology, Mardan (UETM), Pakistan. He is the Director of Postgraduate Studies at UETM and Head of the Antennas & Electrometric Research Group. SadiqUllah received B.Sc. Electrical Engineering from University of Engineering and Technology, Peshawar, Pakistan.  He achieved his M.Sc. in Electrical Engineering from University of Engineering and Technology Taxila, Pakistan. In 2007, he joined the Department of Electronic and Electrical Engineering, at Loughborough University, U.K., and was awarded Ph.D. for his research in the field of design and measurement of metamaterial based antennas in 2010. He worked as an Assistant Manager (Electronics) in a public sector R & D organization in Islamabad, where his main responsibilities were hardware, software co-design, designing and testing of high precession electronics, test equipment. His research mainly focuses on design and measurement of low-profile antennas on electromagnetic Bandgap structures, metasurfaces, multiband antennas, wearable antennas, mmW/THz antennas and 5G antennas. He has worked as a Research Associate at Loughborough University, where he researched on the propagation effects of rain, snow, ice, fog and forest in millimeter wave band. He has published his research in international conferences and Sci-Indexed journals.
讲座内容   The recent trends in the state of the art antennas for current and future communication systems are their wider bandwidth, frequency/polarization/pattern diversity, compact size, higher gain and efficiency. In addition low specific absorption rate (SAR) is also the main requirement for antennas operating in close proximity of human body. Conventional techniques can be used to achieve some of these goals but they are limited in their scope. However if2D-Metamaterials are integrated with the antenna design, these performance metrics can be realized.
  The first part of the presentation covers metamaterial in general, i.e., classification, design, characterization and application. The design and realization of angle insensitive and wideband metasurfaces for polarization dependent applications is another interesting area of electromagnetic (EM) research. Some recently designed polarization dependent metasurfaces will be discussed in detail. The method of simulation and parameter extraction of these surfaces will be briefly covered.
  The second part will cover selected antennas designed for various applications in the microwave, millimeter-wave (mmW) and THz frequency regimes.  Specific results from the recent work of Dr. S. Ullah’s research group on antennas &metasurfaces will be included in this talk.
