群速

• The dispersive characteristic of sws is a very important parameter of the rbwo and rtwt , other parameters such as the phase velocity , group velocity , coupling impedance can be derived from the linear dispersion relation . recently , the photonic crystal have attracted many attentions of the scientists , which has become a hot point of the research , it is also a ps
  周期慢波结构色散特性是研究高功率微波器件的一个重要参量,其他重要特性如相速、群速、耦合阻抗等参量都可以从色散关系衍生出来,准确,快速获得周期电磁结构的色散特性就显得尤为重要。
