Our recent research regarding sheet beam extened interacion oscillators (SB-EIOs) are presented in this paper. In recent years, we have conducted the research of terahertz-band SB-EIOs around two issues: (1) to increase the output power, and (2) to extend the tunable frequency bandwidth. For the first issue, the idea of combining the advantages of a ladder-like interaction circuit (high gain per unit length) and a pseudospark-sourced sheet electron beam (high beam current density and large beam cross-sectional area) is proposed. Such an idea was experimentally verified by using hot-test results. For the second issue, the concept of multiple-mode operation has been proposed to replace the traditional single-mode operation. Such a methodology so far has been initially confirmed by using cold-test results.

Land use and land cover (LULC) is an important factor affecting runoff and sediment yield of watershed. Dongjiang River is the main source of drink water for Hong Kong and cities in the Pearl River Delta Area, which experienced a rapid urbanization and blooming economy growth. Studying the land use changes using time series remote sensing and their influences on runoff and sediment yield in watershed-scale can provide valuable information for the formulation of land use plans in Dongjiang Watershed. This study constructed a SWAT (Soil and Water Assessment Tool) model of the Dongjiang River basin and analyzed the LULC changes from 2001 to 2012 using MODIS land use data products (MCD12Q1). The influence of LULC changes on the runoff and sediment yield in the Dongjiang basin was analyzed by simulating the runoff and sediment yield under different LULC scenarios. Our results show that the main types of land use in the Dongjiang River basin were evergreen woodland, grassland and agricultural land from 2001 to 2012, accounting for more than 80% of the total area of the basin. During the period of study, the evergreen forest land increased by 14.46%, while grassland, agricultural land and mixed forest decreased by 4.78%, 4.54% and 3.97%, respectively. These changes led to an increase of 0.22 mm in the average monthly runoff in the basin, which reached by 2.39 mm in flood season (April-September). At the same time range, the average monthly sediment yield decreased by 0.79 t/ha with a more significant decreasing by 6.29 t/ha in flood season (From April to September). Our results indicate that long term conversions of grassland, agricultural land and mixed forest to evergreen woodland in watershed will lead to the increasing runoff and decrease of sediments of river, which is important for catchment-scale resource planning and environmental management.
土地利用和土地覆被是影响流域产流产沙的重要因素。东江是香港及珠江三角洲城市的主要饮用水源，而珠江三角洲地区正经历着快速的城市化和蓬勃的经济增长。利用时间序列遥感技术研究东江流域土地利用变化及其对流域产流产沙的影响，可为东江流域土地利用规划的制定提供有价值的信息。利用MODIS土地利用数据产品(MCD12Q1)，构建了东江流域SWAT (Soil and Water Assessment Tool)模型，分析了2001 - 2012年东江流域土地利用价值变化。通过模拟不同情景下的径流产沙量，分析了东江流域径流产沙量变化对径流产沙量的影响。结果表明:2001 - 2012年东江流域土地利用类型以常绿林地、草地和农用地为主，占流域总面积的80%以上;研究期间，常绿林地面积增加14.46%，草地、农用地和混交林面积分别减少4.78%、4.54%和3.97%。这些变化导致流域月平均径流量增加0.22 mm，汛期(4 - 9月)增加2.39 mm。同期，月平均产沙量减少0.79 t/ha，汛期(4 - 9月)减少幅度更大，为6.29 t/ha。研究结果表明，流域内草地、农用地和混交林向常绿林地的长期转变将导致河流径流量的增加和沉积物的减少，这对流域尺度的资源规划和环境管理具有重要意义。

In this paper, we implement the high order boundary condition (HOIBC) in the integral equations to solve the scattering problem. We study the HOIBC operators that appear in the boundary integral equations and we propose a discretization of these operators in spaces H(div) and H(curl). Then, we give validations of the HOIBC by calculating the radar cross section (RCS), that show the improvement in accuracy over the standard impedance boundary condition (SIBC). The computation code implements the H-matrix approach with Adaptive Cross Approximation (ACA) and MPI parallelization.

This paper deals with the application of self-accelerating beams for obstacle circumvention in communication applications. Particularly, although recent research works have proposed to take advantage of the self-healing property of self-accelerating beams like the Airy beam to circumvent obstacles and enable data transmission in non-line-of-sight (non-LOS) scenarios, the analysis presented in this paper shows that this is not a viable approach, at least when the transmission aperture dimension is comparable or smaller than that of the obstacle. Ray-optics interpretation, equivalent point source propagation models which take into account the presence of obstacles of different sizes, and full-electromagnetic wave simulation results will be provided to confirm this fact.

In this paper, a D band zero bias detector chip using InGaAs Schottky barrier diode (SBD) is proposed. The Schottky barrier diode with 3.5 THz cut-off frequency and 0.16 eV barrier height is realized based on the low barrier Schottky junction formed by contact between InGaAs and Ti. The detector chip is fabricated on a 50 micron InP substrate using the MMIC technology, and the microstrip structure is realized by processing the metal layer on the back of the InP substrate. The RF grounding of the Schottky barrier diode is completed by connecting the metal through hole with the back metal layer. The experimental results show that the voltage sensitivity of the D band detector chip is more than 2100 V/W in the range of D band, and more than 12000 V/W at 122 GHz, when the input RF power is −30 dBm.

In this paper, the characteristic mode theory (CMT) is applied to the analysis of the ultrawideband (UWB) antennas. The effect of each mode on the radiation of the antenna can be known by analyzing the modal weighting coefficients (MWC). Depending on the location and magnitude of the mode current, additional slots are introduced to block the current. An UWB antenna with three kinds of band-notched antenna is designed.

This paper proposes a kind of broadband metasurfaces that can independently and finely control the amplitudes and phases with a high efficiency for both reflection and transmission modes. A Fabry-Perot (FP) cavity and a metallic dual-split ring (DSR) polarizer are combined to construct each element of the metasuface that has an ultrathin and planar structure. The forward cross-polarization transmission and backward co-polarization reflection can be switched easily by varying the DSR polarizer. It can offer the arbitrary combination of amplitudes within [0, 1] and phases within the range of [0, 360°] for both transmission and reflection modes. The proposed metasurface was applied to design high-gain low-sidelobe transmitarray antenna (TA) and reflectarray antenna (RA). Comparisons between metasurfaces based on the phase control only and those based on the control of both phase and amplitude are studied. Numerical simulation results verify the described superior performance.

Group-velocity dispersion (GVD) engineering is vital to many nonlinear optical phenomena and has been widely used for nonlinear optics. In this work, we propose SiC- and Si3 N4-based waveguides, which are truly dispersion-flattened and simultaneously single-mode. An ultra-low and flat dispersion profile with four zero-dispersion wavelengths (ZDWs) can be obtained over an octave-spanning bandwidth from 1.8 to 3.6 μm. Meanwhile, only TE00 mode is supported in the proposed waveguide over the low-dispersion bandwidth.

In this paper, we propose a wideband and high-gain planar antenna array for millimeter-wave applications. In this array, the slot radiator with a C-shaped and open structure is used as the antenna element. Due to the travelling-wave radiation of the open slot, the slot radiator can produce a wideband radiation and have an impedance bandwidth of 40% with the |S11| below –10dB from 21.6 GHz to 32.6 GHz. The gain of the proposed antenna element is up to 12.5 dBi owning to its large radiation aperture formed by two C-shaped open slot. Based on this wideband and high-gain antenna element, we design an 8 × 8 antenna array with a 1-to-64 SIW full-corporate feed network. The proposed array is fabricated in a two-layer substrate using standard printed circuit board (PCB) technology. The measured results show that the proposed antenna array has an impedance bandwidth of 37% from 21.4 to 31GHz. The measured gain of the proposed array is from 26.3 to 28.4 dBi over the operating bandwidth, with an average radiation efficiency of 70%. With wide bandwidth and the high directive gain, the proposed antenna array is a good candidate for long-distance millimeter-wave communications.
