For the 32-Bit FDTD simulation, observation objects will record the entire time domain response so that spectrum analysis can be performed in analyzer. For 64-Bit FDTD simulation, Observation Points will still record the time domain response in each single point, but Observation Area will perform the spectral analysis during the simulations and save the resulting DFT spectral data only. No time domain response data is stored for Observation Areas, due to its huge volume. For 64bit FDTD simulations, Observation Points or Observation Areas must be present, otherwise no result data will be stored during the simulations.
• Observation Point
Observes the time domain and frequency domain response. The transmission function can be obtained from the Observation Point analysis.
• Observation Area
It is used to compute power transmission ratio, normalized power (power transmission /reflection) versus wavelength and Heating Absorption.
| Step | Action |
