    Abstract: A single-patterned five-band terahertz metamaterial absorber based on simple metal–dielectric–metal sandwich structure is investigated and demonstrated. The numerical simulations reveal the different dependence of the absorption ability on the incident polarization angle, dielectric layer, and structural dimensions of the single pattern. The extracted electric field distribution indicates that the five-band near-perfect absorption performance (average over 98%) mainly originates from the combination of LC, dipole, quadrupole, and high-order resonance. The researches on magnetic field and power loss density distributions further reveal the absorption mechanism. Moreover, additional resonance mode can be excited to form a six-band high-performance absorber only by adjusting some geometric dimensions of the single pattern with multiple resonance modes. The simple method provides us a very good idea to implement a super multi-band absorber. The proposed absorbers here can be applied in massive related fields, such as metamaterial sensors, thermal radiation, and imaging system.

    An ultra-broadband terahertz metamaterial absorber based on split rings array and island-shape structures

    Abstract: An ultra-broadband absorber is achieved by constructing novel island-shape structures on a single-layered broadband absorber. The single-layered absorber contains four same sized metallic split rings with different heights of the base. Its absorption goes beyond 98% from 1.82 THz to 3.70 THz and the full width at half maximum (FWHM) is 102.3% (from 1.47 THz to 4.55 THz), much better than these achieved by assembling multiple nested resonators. Then, by stacking novel island-shape structures over the single-layered absorber, we can excite 1-order magnetic response to precisely add a new peak near the broadband and enhance the bandwidth. The multi-layered absorber covers a bandwidth of 3.51 THz (the absorption over 90% from 1.23 THz to 4.74 THz) and the FWHM is up to 139.7%, far larger than previous reported results. It also performs well at considerably large oblique incident angles. Moreover, the island-shape structures have the potential to be applied in some other single-layered absorbers to widen their bandwidth.

    Abstract: Community detection is of great significance in analyzing the network structures. However, real networks usually contain missing links and spurious interactions, which affect the accuracy of community detection results. In this paper, we aim to find out the regularity of the impact on community detection when links are deleted from or added to the network. To address this problem, we propose degree-related link perturbation (DRLP) methods for the tasks of both deleting and adding links, and the random perturbation methods are also be employed. Then, we evaluate the impact of perturbation methods on community detection and draw some conclusions. Finally, extensive experiments conducted on six real-world networks demonstrate the existence of the regularity. The perturbation of deleting and adding links can lead to continuous rise and decline of modularity, respectively, which is also instructive to change the results of community detection purposefully.

    STUDY ON DEEP TRAP STATES IN POLYMERS BY PHOTO-STIMULATED DISCHARGE BASED ON THE OPO LASER

    Abstract: A photo-stimulated discharge (PSD) method is more effective than thermal methods to characterize the deep space charge traps in dielectric materials. In this paper, a new PSD measuring system was first built up based on the optical parametric oscillator laser. The laser can generate continuously tunable wavelengths whose range are 210–420 nm and with average output pulse energy 2.3 mJ. The system overcomes the shortcoming of weak output energy in past experiments, especially in the range of ultraviolet band. The PSD current spectra of PET were measured by this system. The results show that the energy level of charge traps in the PET film is mainly distributed in 4.08~5.18 eV, and the trap density maximum is at 4.22 eV. These data can provide the experimental basis for further research and improvement on electrical properties of materials.

    Abstract: The purity evaluation of deionized (DI) water is highly desirable for VLSI or ULSI industry, as the traditional "reverse osmosis filter" cannot always meet the requirement towards the DI water. The filtered DI water may still contain many contaminations which are not up to the standard for the wet cleaning of wafer surface. A novel method is presented by analyzing the residues of a water droplet after the low-temperature evaporation. The contamination contained in the water will remain during the gasification. By analyzing the residual contamination's morphology, the purity of the DI water can be estimated by employing merely a 3D laser microscope. Compared to the traditional fluorescence detecting system for water quality monitoring, it is simpler and has a lower cost. The paper describes an excellent water detection method which is meaningful for preparing ultra-pure water. Experimental results have shown that the deionized distilled (DID) water can repeatedly get a higher purity using this detection method. The DID water can be applied to the wet cleaning of wafer surface, preparation of chemical reagents and many other aspects.

    Abstract: In recent years, metasurfaces have widely been studied due to their ability to offer a spatially varying phase response, low losses, ultrathin size, and easy fabrication. In this paper, a gradient phase discontinuity all-dielectric metasurface consisting of arrays of silicon cube resonator is designed. By adjusting the dimension of the silicon cube resonator, a [Formula: see text] transmission phase covered from [Formula: see text] to [Formula: see text] with [Formula: see text] phase intervals is realized in a frequency from 9.7 GHz to 11.8 GHz. We demonstrate the all-dielectric metasurface can produce the anomalous refraction, vortex beams, and wave-focusing in the microwave and infrared band, respectively. It can be expected that the proposed metasurfaces can find wide applications in communication, designing integrated optical devices, and focusing lenses.
