Optical characterization of high and low resistive silicon samples suitable for reconfigurable antenna design
(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
(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 ... -
Parasitic effects of the metallic towers on the characteristics of the broadcast antennas
(John Wiley and Sons, 2018)In this article, we use a tool NEC (Numerical Electromagnetic Code) to model antenna on top of a tower structure. Simulation results for the parasitic effect of the tower on characteristics of broadcast DVB-T (Digital Video ... -
Production of natural chitin film from pupal shell of moth: Fabrication of plasmonic surfaces for SERS-based sensing applications
(Elsevier Ltd, 2021-06-15)Commercially available types of chitin or chitin isolate are usually in powder form and are nanofibrous in microstructure. However, the surface characteristics of natural chitin in the body of insects are currently ... -
VHF suspended plate transmitter antenna design for DVB-T and DAB-T
(John Wiley and Sons, 2018)This paper presents the design of stacked suspended plate transmitter antenna for digital video and audio broadcasting. Contrary to conventional dipole structures, we have designed the antenna in VHF band (174-254 MHz) ...
