Our Analyzer provides a number of tools allowing for evaluation simulation results.

Observation Point

StepAction
1Select “Observation Area Analysis” under the “Tools” menu in the Analyzer.

Observation Point dialog box appears

2To observe the time domain response in the observation point, check the observation point object, select the field components button, and select Time radio button.  (See Figure 9)

FDTD - Figure 9 Time domain response in observation point

3To get the transmission /reflection function response in an observation point, select Frequency FDT radio button. And type the following values (See Figure 10)

Minimum wavelength: 1.3

Maximum wavelength: 1.6

Sample point: 1000

Normalize with: InputPlane1

Click Update Graph button

Field pattern in Observation Area

StepAction
1Select Observation Area in Observation Area Analysis dialog box.
2Select “ObservationArea2” in the observation area check list
3Select wavelength 1.5 from the l/f list box

Note:

•     Click l/f button to alternate the unit between wavelength and frequency

•     The wavelength or frequency value is pre-set in the spectrum setting dialog box (refer to Figure 2)

4Click Update Graph (see Figure 11)
5Repeat step 2 to step 4 for ObservationArea1 (See Figure 12)

Power transmission/reflection function

StepAction
1Select Observation Area in Observation Area Analysis dialog box.
2Select “ObservationArea2” in the observation area check list
3Select Power Spectrum button, Power Spectrum dialog box appears
4Check “normalize with” checkbox and click Calculate button, Power Transmission spectrum appears, (refer to Figure 13)

Note:

•     In order to perform power calculations, the necessary field components have to be selected for different polarization power.

•     When an observation area is behind the input wave, it can detect the reflection power spectrum.
