The crystal structure of the samples is characterized by XRD pattern. From Fig.2a, all samples show amorphous carbon with a wide diffraction peak at around 26°, consisted with the result of HRTEM image (Fig.1g). The typical diffraction peak of GO disappeared at 9.8°, indicating the GO wa...
Figure 1. Schematic diagram showing the pathways of the global navigation satellite system (GNSS) signal used by the tracking device (TD) and the transfer of the positioning data via a mobile network to a handheld device (HHD) (pathway A) or via licence-exempt frequencies (WLAN, Bluetooth) ...
Figure 4. Schematic diagram of the AFEM-3 system structure. 3.1. Sensor Head The key to target detection using the frequency domain electromagnetic method lies in how to extract the weak induced secondary field signal for analysis and processing in the presence of a strong transmission magnetic ...
Fourier decomposition is performed to obtain the spectrum, as shown in Figure 6b. Compared with the electromagnetic force spectrum diagram under the fundamental current drive, the electromagnetic force spectrum diagram under the frequency converter drive obviously adds a lot of electromagnetic force ...
Time–frequency spectrum obtained by EWT–HT based on STFT and closing operation. 4. EWT–HT Application in Time–Frequency Analysis for EMR Waveform of Rock Fracture 4.1. Experimental System The schematic diagram of the experimental system is shown in Figure 12. The YAW–600 pressure tester wa...
It is noted that HPEMPs have a strong energy and wide frequency spectrum, which not only can cause direct disability to the electronic systems of vehicles but also can interfere with or damage the electronic control system by powerful coupling through windows, apertures, or antennas [3,4,5]....
