- property CircularWaveguide.kc: Union[Number, Sequence[Number], ndarray]¶
Cut-off wave number.
Defined as
\[k_c = \frac{u_{mn}}{R}\]where R is the radius of the waveguide, and u_mn is:
the n-th root of the m-th Bessel function for ‘tm’ mode
the n-th root of the Derivative of the m-th Bessel function for ‘te’ mode.
- Returns
kc – cut-off wavenumber
- Return type
