acdecom.WaveGuide.get_eigenvalue_rect

WaveGuide.get_eigenvalue_rect(m, n, **kwargs)

Returns the eigenvalue of the (m,n)-mode for a rectangular duct.

\[\kappa_{mn} = \pi (\frac{n}{a} + \frac{m}{b})\]

Parameters

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

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

• kwargs (additional arguments) –

Returns

The eigenvalue of the (m,n)-mode.

Return type

float or complex
