Development of narrowband 92 MHz Yagi-Uda antenna for use in passive radar applications
(Ieee, 2019)
The Yagi-Uda antennas have a wide range of applications ranging from radio broadcasting to passive radar systems. in this study, a Yagi-Uda antenna was developed to be used as a receiving antenna in an FM based passive ...
Extraction of theoretical bit and symbol error rates of dual carrier modulation with QPSK
(Ieee, 2019)
Dual carrier modulation (DCM) improves transmission performance in wireless communication channels by using it with orthogonal frequency-division multiplexing (OFDM). in the literature, DCM is proposed to use in ultra-wideband ...
QPSK-dual carrier modulation for ultra-wideband communication in body area network channels
(2019)
Dual carrier modulation (DCM) using orthogonal frequency-division multiplexing (OFDM) improves the performance in multipath fading channels. In the literature DCM is proposed with 16-quadrature amplitude modulation (16QAM) ...
Fabrication and characterization of Au/n-ZnO/p-Si/Al sandwich device with Sol-gel spin coating method
(Springer, 2019)
ZnO thin films with the n-type properties were obtained on the p-Si substrates for multi-layered sandwich device depositing by sol-gel method. Au and Al were conducted on two side of hetero-junction by PVD technique. From ...
Widely-tunable dual-wavelength Tm:YLF, Tm:LuAG, and Tm:YAG lasers
(Institute of Electrical and Electronics Engineers Inc., 2019)
Dual-wavelength operation of lasers are attractive for many applications such as coherent terahertz wave generation, ultrahigh pulse repetition rate creation by optical beating, and laser ranging. Several methods could be ...
Efficient Tm:YAG and Tm:LuAG lasers pumped by 681 nm tapered diodes
(OSA - The Optical Society, 2019)
In this paper, we present highly efficient continuous-wave (cw) laser operation of Tm:YAG and Tm:LuAG lasers pumped by high-brightness red tapered diodes. The single-emitter tapered diode lasers (TDLs) provide up to 1 W ...
Efficient Tm:YAG and Tm:LuAG lasers pumped by red tapered diodes - 2
(OSA - The Optical Society, 2019)
Eye-safe, diode-pumped all-solid-state lasers working in the 2 ?m region are favourable for many applications including remote sensing, medicine, and gas sensing. Tm-doped crystals such as Tm:YAG and Tm:LuAG are among the ...
