Abstract :
A direct technique of Q-factor extraction based on space-selective integration of dissipated power and electromagnetic energy is proposed, implemented in the FDTD software, and validated against analytical solutions and Prony method. An advantage of this technique over Prony is that losses caused by various materials and / or in various parts of the circuit can be independently evaluated during one FDTD simulation. Its disadvantage is the necessity of a separate simulation for each eigenmode.
