The radiation pattern in the near and far field of each frequency component of the spectrum of current pulse on a transmission line. 传输线上脉波电流频谱中各频率成份在远近场区中场型之比较。
On the basis of analyses, it is shown that the radiation with low frequency by relativistic electrons will form Rayleigh-Jeans spectrum in optically thick medium. 由分析可知,在光学厚的介质中麦氏分布的极端相对论电子在磁场中能产生同步加速辐射,其辐射谱为瑞利-金斯谱。
THz radiation has broad application prospects in lots of fields owing to its special position in the frequency spectrum. 太赫兹(THz)辐射由于所处的频谱位置的特殊性,在许多方面有广阔的应用前景。
