    • Computer aided frequency planning for the radio and TV broadcasts 

      Altıntaş, Ayhan; Ocalı, O.; Topçu, Satılmış; Tanyer, S. G.; Köymen, Hayrettin (Institute of Electrical and Electronics Engineers, 1996-06)
      The frequency planning of the VHF and UHF broadcasts in Turkey is described. This planning is done with the aid of computer databases and digital terrain map. The frequency offset is applied whenever applicable to increase ...
    • Optical characterization of high and low resistive silicon samples suitable for reconfigurable antenna design 

      Ali, A.; Topalli, K.; Ramzan, M.; Khan, Talha Masood; Altıntaş, Ayhan; Colantonio, P. (Wiley Periodicals, Inc., 2018)
      Highly resistive (HR) silicon (Si) can behave as a switch when illuminated by optical source of suitable wavelength. Different reconfigurable passive structures, such as filters, waveguides, and antennas, can be constructed ...
    • Optically reconfigurable planar monopole antenna for cognitive radio application 

      Ali, A.; Topalli, K.; Ramzan, M.; Alibakhshikenari, M.; Khan, Talha Masood; Altıntaş, Ayhan; Colantonio, P. (Wiley Periodicals, Inc., 2019)
      Frequency reconfigurable antenna is one of the important elements needed for cognitive radio application. Such antenna can be designed using highly resistive (HR) silicon (Si) operating as an optical switch. This letter ...
