Excellent Microwave Absorption Properties Derived from the Synthesis of Hollow Fe3o4@Reduced Graphite Oxide (RGO) Nanocomposites

Nanomaterials (2019)

Guangzhen Cui Yanli Lu Wei Zhou Xuliang Lv Jiangnan Hu

Magnetic nanoparticles, such as Fe₃O₄ and Co₃O₄, play a vital role in the research on advanced microwave absorbing materials, even if problems such as high density and narrow band impedance matching are still unsolved. Herein, the study of lightweight hollow Fe₃O₄@reduced graphite oxide (RGO) nanocomposites synthesized via the solvothermal method is presented. The microstructure and crystal morphology of the materials were characterized by X-ray diffractometer (XRD), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) analyses. Single crystalline hollow Fe₃O₄ spheres were grown onto RGO flakes, leading to the formation of heterojunction, which further influenced the microwave absorption properties. The latter were evaluated by standard microwave characterization in the frequency range of 2⁻18 GHz. It was found that, for a specific Fe₃O₄@0.125 g RGO composite, the minimum reflection loss can reach -41.89 dB at 6.7 GHz, while the reflection loss was less than -10 dB from 3.4 GHz to 13.6 GHz for a nanocomposite sample thickness in the range of 1⁻4 mm. The combination of these two materials thus proved to give remarkable microwave absorption properties, owing to enhanced magnetic losses and favorable impedance matching conditions.

Sufficient and comprehensive measurement of multi-band camouflage screen performance applying bi-objective super-efficiency DEA

Xuliang Lv Ling Li Weidong Xu Xianhui Rong

In this paper, we measure performance of multiband camouflage screen by a new hybrid model based on bi-objective super-efficiency DEA. We propose super-efficiency DEA theory to improve conventional DEA with non-Archimedean infinitesimal, and then we take bi-objective issue into consideration to formulate a hybrid model. The proposed model has three main advantages in assessing multi-band camouflage screen performance: (i) it applies super-efficiency DEA to realize sufficient ranking of performances; (ii) non-Archimedean infinitesimal utilized in DEA can give slacks and projections, which provides optimal condition those indexes of inefficient DMUs can be attained; (iii) bi-objective DEA can offer more comprehensive evaluation from both input-orientated and output-orientated perspectives. We illustrate the application of the proposed approach by a numerical example with a set of experimental data. The example shows the effectiveness and practicability of the new approach.

Research on Optimization Method and Experiment of Digital Camouflage Pattern

DEStech Transactions on Computer Science and Engineering (2018)

Qi Jia ZAI-YUAN LIU Weidong Xu Jianghua Hu Xuliang Lv

The design of digital camouflage pattern directly affects the camouflage effect. In order to solve the problem of digital camouflage effect evaluation and the optimization of digital pattern, three index features, including extraction brightness contrast, color feature and orientation feature, are selected to construct the synthetic evaluation index system of digital camouflage. A model of digital camouflage effect evaluation based on multi index grey clustering algorithm is established. Then he model is programmed with MATLAB software to compare the camouflage effect of different digital camouflage patterns and choose the best digital camouflage pattern. Finally, the virtual scene method is used to detect the subjective camouflage effect of digital camouflage pattern. The results show that the synthetic evaluation index system of digital camouflage based on background has certain feasibility, and the result of operation is more accurate and effective, so it can realize the optimization of digital camouflage.

Research on measurement method of optical transmittance of the artificial fog

Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE (2016)

Jianghua Hu Chaochao Jian Guangzhen Cui Xuliang Lv Xianhui Rong

The attenuation of light was a common result that the light was absorbed and scattered by the artificial fog particles when it transmitted in the artificial fog. The absorbing attenuation process of light transmission in the artificial fog was that the artificial fog converting incident light energy into other forms of internal energy (such as heat energy). The scattering attenuation process of light transmission in the artificial fog was that the artificial fog particles intercepting incident radiation energy to form infrasonic waves and to radiate peripherally so that the incident light energy was reduced on the original direction of transmission. The mechanism of light transmission attenuation in the artificial fog was analyzed. The formation method of the artificial fog was expounded and the measuring principle of the artificial fog transmittance was described. A simple and reliable measurement method of the optical transmittance of the artificial fog in the fog chamber was proposed. The optical transmittance measurement system of the artificial fog was built by using incandescent lamp, power with steady current and voltage, lens, selenium photocell, micro-galvanometer, optical bench, hygrothermograph, humidifier, etc. Under different conditions of humidity, the optical transmittance of the artificial fog was obtained on the basis of measuring the photocurrent before the fog was formed in the fog chamber. The test results show that the measurement system is stable and reliable. During the 43 minutes after the artificial fog was formed, the optical transmittance of the artificial fog was averagely less than 5 percent and the optical transmittance increased gradually with the extension of time. In addition, the optical transmittance of artificial fog didn't produce obvious change while air humidity increased from 68.7% to 85%. The measurement system can be used to measure transmittance of smoke screen, water mist and other aerosol.
