Post-Simulation Data Analysis

Compatibility:

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

Observation Point

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

Observation Point dialog box appears

2 To 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)

3 To 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

Step Action
1 Select Observation Area in Observation Area Analysis dialog box.
2 Select “ObservationArea2” in the observation area check list
3 Select 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)

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

Power transmission/reflection function

Step Action
1 Select Observation Area in Observation Area Analysis dialog box.
2 Select “ObservationArea2” in the observation area check list
3 Select Power Spectrum button, Power Spectrum dialog box appears
4 Check “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.
