| 摘 要： | 太赫兹片上系统是一种将太赫兹产生和探测装置以及波导传输装置集成在同一基片上的设计，应用于晶体材料的共振吸收以实现对太赫兹时域光谱的探测。太赫兹产生与探测装置都由光电导天线构成，波导传输装置由微带线构成。微带线是一种能够传输高频电磁波的波导结构，但相比于自由空间波导具有高损耗和散射特性。为了研究微带线的结构参数对太赫兹波传输损耗的影响，采用模拟仿真的方法，得出了传输损耗随着传输长度和频率的增加而增加，随着微带线金属层厚度与介质层厚度的增加而减少的规律，从而证明了传输损耗的减少能够通过合理设计微带线结构来实现。

| Abstract: | On-chip terahertz system is a design which integrates terahertz generation device, detection device and waveguide transmission device on to the same substrate. It is utilized to measure the spectral absorption of crystal materials to achieve the function of terahertz time-domain spectroscopy (THz-TDS) system. The terahertz generation device and detection device are photoconductive antennas and the waveguide transmission device is Microstrip Line(MSL). MSL can transmit high frequency electromagnetic waves, but it also shows a higher attenuation and dispersion compared with the free-space waveguide. In order to study the influence of the structural parameters of microstrip lines on the transmission loss of terahertz wave, simulation is performed to show that the transmission loss increases with the increase of transmission length and frequency. At the same time, with the increase of the thickness of metal layer and dielectric layer, the transmission loss reduces gradually, thus proving that the reduction of transmission loss can be achieved through the rational design of microstrip line structure. |
