acdecom.WaveGuide.get_K0

WaveGuide.get_K0(m, n, f, **kwargs)

Placeholder for the dissipation function for the wavenumber. When the object is initiated, this function may be overwritten either by one of the predefined dissipation functions WaveGuide.getK0_kirchoff(), WaveGuide.getK0_dokumaci(), meth:.WaveGuide.get_K0_stinso_rect, meth:.WaveGuide.get_K0_stinson_cricular or a custom function.

Parameters

  • m (int or array_like) – Mode-order in the first direction. If the waveguide is circular, m indicates the circumferential mode-order. The plane wave has the order 0.

  • n (int or array_like) – Mode-order in the second direction. If the waveguide is circular, n indicates the radial mode-order. The plane wave has the order 0.

  • f (float, optional) – Frequency in Hz.

  • kwargs (additional arguments) –

Returns

The dissipation factor of the (m,n)-mode at the frequency f [Hz].

Return type

complex
