  太赫兹波
    Transverse Mode Distribution of THz Wave by THz Imaging Technology
    太赫兹波传播过程中横模分布的成像
短句来源
    In addition, we also get several conclusions as follows: 1) Power of TM mode THz wave reaches a maximum when laser incident angle nears the Brewster angle;
    此外,还有以下几个结论:1)当激光脉冲入射角在布鲁斯特角附近时,磁场增强后的太赫兹波中TM模分量功率达到最大值;
短句来源
    The results show that the shapes of the transverse modes of THz wave in different positions around the focus have much difference. To the maximum wavelength of about(1.5 mm) of THz wave in the system,the minimum diameter of THz beam at the focus point is around(1.0 mm.) The results provide a basic reference for further application of THz Spectroscopy and THz Imaging.
    利用“狭缝法"测量了太赫兹光束的束宽。结果表明,太赫兹波在焦点附近不同位置的横向分布有较大差异,在焦点处对应于最长波长1.5 mm的最小光斑直径约为1.0 mm,这说明太赫兹波的聚焦有一定的限度。实验确定了系统中放置样品的最佳位置,对开展太赫兹光谱和成像研究有参考价值。

  thz wave
Frequency tunable high-power THz wave generation has been successfully achieved utilizing lattice resonance of LiNbO3 and GaP crystals, respectively.
      
The terahertz region is between the optical wave and the so-called microwaves; it had not been studied until 1963, when Nishizawa started the development of a THz wave generation based on the character of lattice or molecular vibrations.
      
THz wave sensing for petroleum industrial applications
      
In addition, a wide band frequency tunable electromagnetic wave source may be developed at THz wave region by providing a low loss microstrip line resonator with field emission array due to the gate voltage dependent phase constant of the line.
      
The amplification constant of 28dB/mm is achieved at THz wave region by applying the monotron to a distributed amplifier and is sufficient to overcome power loss in a transmission line.
