# skrf.media.cpw.CPW.v_p¶

property CPW.v_p: ndarray

Complex phase velocity (in m/s).

$j \cdot \omega / \gamma$

Notes

The j is used so that real phase velocity corresponds to propagation

where:

• $$\omega$$ is angular frequency (rad/s),

• $$\gamma$$ is complex propagation constant (rad/m)

Returns

v_p

Return type

numpy.ndarray

propagation_constant, gamma
