Abstract

Quasi-Normal Modes (QNMs) are a key concept in reduced-order models. In this thesis, we use Finite-Difference approach to create a discretized model of an open electromagnetic system in order to identify its QNMs and the Perfectly Matched Layer (PML) modes. We develop a structure of the QNMs and the PML modes and identify different regions of the eigenvalue distribution in our system. We validate the idea of dominant QNMs by using the identified QNMs to get the solution that was obtained using the Finite-Difference method.
