| 1 | 无背钻孔的微波板间垂直互连研究显示文摘多层板加工时一般通过背钻孔制作准同轴线垂直互连的中心孔。文中建立了一种新的准同轴线垂直过渡模型,该模型不需要通过背钻孔制作中心孔,直接由金属化通孔实现。制作工艺简单,垂直过渡性能稳定、一致性好。试验证明该形式垂直过渡满足工程需求,简化了制作工艺。 | 凌天庆 | 2014 | 现代雷达2014，36，6： | 10 |
| 2 | 孔型对金属-介质-金属三明治结构超材料的透射率和负折射率的影响(英文)显示文摘通过改变长方形孔的长度,利用数值模拟研究了金属-介质-金属三明治结构超材料的透射率,负折射(NRI)率和品质因数(FOM)等性质.研究结果表明,随着长方形孔的长度的增大,低频透射峰和最大透射峰都出现了红移现象.长方形孔的负折射率和负折射带宽则随着长方形孔的长度的增大而减小.这意味着可以通过调节金属-介质-金属三明治结构超材料的孔阵列的长度获得较高的透射率或者负折射率.这些结果为开发太赫兹范围的光电器件提供可能的理论. | 钟敏 | 2014 | 红外与毫米波学报2014，33，3： | 3 |
| 3 | Research of the terahertz dual-band notch filter based on FSS structures显示文摘In this paper,a dual-band notch filter for two-layer frequency selective surface(FSS)at terahertz(THz)frequency with high filtering performance has been realized on high-resistivity silicon substrates.With periodic metallic resonators patterned on the silicon wafer,the designed filter can provide two tunable resonant frequencies for terahertz application.The transmission response was improved by introducing an extra surrounding pattern around the T-shaped structure,and the location of transmission drop was tuned independently with geometric parameters.Simulated by finite-integral time-domain method,the filter is designed to operate between 0.2 and 0.6 THz with dual-band band-stop performance,a salient feature of this design is making the low sensitivity of its frequency response to the incident angles,which allows to place the filter close to the radiation source with spherical wave fronts.The proposed structures were fabricated using photolithography and tested by THz time-domain spectroscopy system.Experimental results show that the transmission response has more than 12 and 32 dB rejections near 285 and 460 GHz respectively,which is in good agreement with the simulation result. | ZHANG JinLing ZHANG Yu GAO Ke ZHAO GuoZhong | 2013 | Chinese Science Bulletin2013，58，36： | 1 |
| 4 | Influence of the amplitude ratio between two terahertz pulses on two-dimensional spectroscopy显示文摘The influence of the amplitude ratio between the two THz pulses on two-dimension THz spectroscopy(2DTS)has been studied theoretically via a classical method in which the expressions for the second-order nonlinearity were derived using perturbation approach,and the THz pulses were not treated as a delta function.Three types of nonlinear sources i.e.,anharmonicity,nonlinear damping,and nonlinear coupling,are considered in a single mode system.The simulation results demonstrated that the amplitude ratio had a notable influence on the 2DTSs,and different sources have different influences.This study is promising for guiding future experiments. | Jiangsheng Hu Jinsong Liu Huquan Li Kejia Wang Zhengang Yang Shenglie Wang | 2014 | Chinese Science Bulletin2014，59，2： | 1 |

| 6 | Optical bistability based on surface plasmon coupled between a noble metal film and a metal grating involving Kerr materials显示文摘A phenomenon about optical bistability is successfully investigated in a layered structure consisting of a silver film with Kerr medium and a silver grating sandwiched between semi-infinite linear dielectrics.This type of structure can lead to the optical bistability phenomena occurring in reflection and transmission.There exists an optimal thickness of the metal grating that can cut off the effect of the near-field enhancement and may have the lowest effect on conversion from surface plasmon to light.This structure can realize the functions of the beam splitter and the polarization splitter and will be essential for future classical and quantum information processing. | SONG Gang WU Chao ZHOU YanPing YU Li XIAO JingHua | 2013 | Science China(Physics,Mechanics & Astronomy)2013，56，11： | 0 |
