Polycarbonate + Acrylonitrile-Butadiene-Styrene (PC ABS) is a typical non-metallic material used for electric meter enclosures, characterized by its corrosion resistance, excellent insulation properties, and lightweight nature, making it widely applicable in power supply systems. However, prolonged exposure to outdoor environments often leads performance degradation, which can affect normal usage. Therefore, developing rapid detection technologies timely identify rectify potential faults...
The surface acoustic wave (SAW) technology has been widely used for hazardous gas detection, but the low sensitivity, poor selectivity, long response/recovery time, and signal "false positives" of sensors have limited its application gas-phase explosives detection. In this paper, a composite sensor with frequency-resistance dual-signal display was designed by transferring 25 layers graphene (rGO) in sensing area SAW device coupling p-aminothiophenol (PATP)-modified gold nanoparticles...
Surface acoustic wave (SAW) devices are extensively used to detect various gaseous chemicals, owing their wireless passive potential and single-signal display. However, the sensitivity, selectivity, long response time of sensitive layers limit use in detecting explosive gases. In this study, we developed a 2,4,6-trinitrotoluene (TNT) gas sensor based on SAW device with GO/PDEA/AuNR/PATP nanocomposites. The GO/PDEA/AuNR/PATP-SAW recorded considerable negative frequency shift (−70.67 kHz) 80...
In this paper, carbon quantum dot-labelled β-lactoglobulin antibodies were used for refractive index magnification, and was detected by angle spectroscopy. method, the detection light is provided a He-Ne laser whose central wavelength same as that of porous silicon microcavity device, source changed to parallel beam illuminate microcavity' surface collimating expansion, reflected received on detector. The corresponding smallest luminous intensity before after onset immune response measured...
Recently reported plasmon-induced transparency (PIT) in metamaterials endows the optical structures classical systems with quantum effects. In particular, nonreconfigurable nature makes multifunctional applications of PIT effects terahertz communications and networks remain a great challenge. Here, we present an ultrafast process-selectable modulation effect. By incorporating silicon islands into diatomic metamaterials, effect is modulated reversely, depending on vertical horizontal...
The time base drift is a key factor that influences the sampling oscilloscope to measure high speed pulse signal precisely, so must be removed as far possible. Cross-correlation algorithm an alternative method remove effectively. First, this paper does computer simulation, then use do research on original data collected when establishing national parameters primary standard. Both results of simulation and show cross-correlation can
The electromagnetic coupling characteristics of a computer box under the high-power microwave (HPM) which includes narrow-band and ultra-wideband HPM are studied. simulations radiation field in show that optical drive floppy disk main channels through penetrates. cut-off frequency this corresponding dielectric waveguide resonant frequencies on is enhanced. induced current cable peak value decreases with increasing frequency. At same time, damage effect experiments carried out thresholds...
The optical filters are studied according to the applications of photonic-assisted radio frequency (RF) signal gereration and all coherent processing. Firstly, finite impulse response (FIR) filter is analyzed theoretically. And it points out that advantages FIR lies in reconfiguration, real coefficients linear-phase which could guarantee coherence ultrashort pulse. Based on this, specific for free spectral range (FSR) broadening sinusoidal generation designed simulated. results simulation...

Broadband radio frequency signal generation based on ultrafast optical pulse shaping, which is a typical microwave photonic technology, has been performed. The starts from our home-made mode-locked laser repetition rate of ~171 MHz and spans 1524 nm to 1593 nm. Following the MLL an amplifier makes up for loss link. A commercial shaper introduced flatten shape spectrum pulse. However, it results in additionally cutoff. Only C-band (5 THz bandwidth) used efficiently waste resources. Then,...
