medium frequency propagation

基本解释

Phenomenon of the change in velocity of propagation of monochromatic radiations in a medium as a function of the frequency of these radiations.
在介质中传播的单色光改变其传输速度的现象，并由该辐射的频率所决定的。
To study propagation characteristic of radar wave in a dispersive medium, frequency- dependent flux density D was introduced, and electromagnetic field E and flux density D were normalized.
考虑频散介质的电磁波传播，引入随频率变化的电位移矢量D，并对电场强度E和电位移D进行标准化。
The propagation velocity of elastic wave with different frequencies in same medium is various, which is called dispersive problem of frequency.
相同介质中不同频率的弹性波传播速度是有差异的，即频散问题。
