These advanced fields belong to tidy3d.rf.TerminalComponentModeler (opens new window).
# Excitation source time
Controls the source-time settings used for RF excitations.
remove_dc_component: Toggle whether to remove the DC component in the Gaussian pulse spectrum.
custom_source_time: Optional custom source time dependence used for the RF excitations.
- See Custom Source Time.
# Port excitation
Controls which port excitations are simulated or inferred.
run_only: Optional list of S-matrix indices that define which port simulations to run.
element_mappings: S-matrix element mappings used to skip simulations whose results can be inferred from another matrix element.
- See Port excitation.
# S-parameter settings
Controls how S-parameters are computed and post-processed.
assume_ideal_excitation: Toggle how incident wave amplitudes are computed for S-parameter calculation.
s_param_def: Wave definition used to compute scattering parameters.
low_freq_smoothing: Optional low-frequency smoothing parameters used by the terminal component simulation.
- See S-parameter settings.
# Structure priority
Controls the priority mode for structures without an explicit priority.
structure_priority_mode (Type): Priority mode used for structures with no explicit priority.
- See Structure priority.
