skrf.media.circularWaveguide.CircularWaveguide.gamma

property CircularWaveguide.gamma: Number | Sequence[Number] | ndarray

The propagation constant (aka Longitudinal wave number)

Defined as

\[k_z = \pm j \sqrt {k_0^2 - k_c^2}\]

This is:

• IMAGINARY for propagating modes

• REAL for non-propagating modes,

Returns:

gamma – The propagation constant

Return type:

number
