Abstract :
We present a novel approach for extracting the modal parameters of high frequency components and the sensitivity of there parameters using only few time iterations of an FDTD simulation. An adapted version of the matrix pencil method is utilized for efficient extraction of the modal parameters. Using our approach, the modal parameters of all the guided and leaky modes are extracted over the frequency band of interest in a very efficient manner.
