| 摘 要： | 本文用快速傅里叶变换对LTGaAs衬底共面微带传输线光生超短电脉冲的时域传输特性进行了数值计算结果表明,THz以上高频范围的模式色散、LTGaAs衬底切伦科夫辐射衰减使超短电脉冲信号沿LTGaAs衬底共面微带传输线超传输时波形畸变,初始光生电脉冲越窄,则信号波形畸变越严重减簿衬底厚度可降低LTGaAs衬底共面微带传输线的模式色散和辐射衰减,有利于改善LTGaAs衬底共面微带传输线亚皮秒超短电脉冲的传输特性.

| Abstract: | Based on the dispersion and attenuation data obtained from the semiempirical dispersion formula for coplanar transmission lines,the propagation of ultrashort electrical pulses along coplanar striplines on LT GaAs have been stimulated in the time domain by the fast Fourier transform numerically in this paper.It has been shown that the modal dispersion and Cerenkov electromagnetic radiation in the substrate at the terahertz regime dominate the evolution of the pulses propagating in the coplanar striplines,and the shorter pulses will experience the more serious distortion that can be greatly reduced by using a superstrate of the same substrate. |
