WaveGuide.get_kappa(m, n)

Returns the eigenvalues of the (m,n)-mode. This method picks the eigenvalues from a pre-calculated eigenvalue matrix, which makes computations in larger data sets more efficient. For the computation of the eigenvalue, see WaveGuide.get_eigenvalue() .

Parameters

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

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

Returns

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

Return type

float or complex
