Q-Values

The quality factor Q is defined as

$$Q = \frac{\omega W}{P}$$ (4.1)

where

• $\omega$ is the circular resonant frequency,
• $W$ is the total stored energy,
• $P$ is the total power loss due to currents in lossy materials.

In the section -wlosses we compute the wall losses via the perturbation formula. In the section -energy we compute the stored energy in the h-field.
