7.2     Power dissipated results

After checking the Pdiss [W] option, the Pdiss frame shows the results of integrating dissipated power in [W].

At each iteration the software performs the following operations:

• sums up electric power dissipated in all FDTD cells (current Electric Pdiss),

• sums up magnetic power dissipated in all FDTD cells (current Magnetic Pdiss); Note that the power dissipated in lossy metals is considered as Magnetic Pdiss. In future versions the amount of power dissipated in lossy metals will be also given as a separate component Metallic Pdiss, what will allow to split the power dissipated due to metallic and magnetic losses.

• adds up current Electric Pdiss and current Magnetic Pdiss (current Total Pdiss).

Then it compares current value of each quantity to its time-minimum (MIN) and time-maximum (MAX), appropriately modifies MIN or MAX, and re-calculates time-average (AVR) defined as:

AVR = 0.5 (MIN + MAX)

The information about FDTD iterations is given in the status bar.

Detailed discussion regarding power dissipated calculation is given in Power dissipated, energy stored and Q-factors.
