Abstract :
The finite-difference time domain (FDTD) technique and the Pade approximation with Baker´s algorithm are used to calculate the mode frequencies and quality factors of cavities. Comparing with the fast Fourier transformation/Pade method, we find that the Pade approximation and the Baker´s algorithm can obtain exact resonant frequencies and quality factors based on a much shorter time record of the FDTD output.
