acdecom.WaveGuide.K0_stinson_rect

WaveGuide.K0_stinson_rect(m, n, f, **kwargs)

Dissipation function for the wavenumber based on Stinson’s thermo-viscous dissipation in rectangular waveguides without flow.

Parameters

• m (int or array_like) – Mode-order in x-direction. The plane wave has the order 0.

• n (int or array_like) – Mode-order in y-direction. The plane wave has the order 0.

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

• elements (int, optional) – Number of elements used for the series expension. Higher values give more accurate results, but take longer to compute. Defaults to 150.

• kwargs (additional arguments) –

Returns

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

Return type

complex
