Abstract :
It is very important to obtain the natural frequencies (poles) of the scattering body in the singularity expansion method (SEM). In the Letter, the Kuhn algorithm is introduced to find the SEM poles. The result shows that the Kuhn algorithm can be efficient in determining the poles of complex scatterers.
