tidy3d.ChargeInsulatorMedium

class ChargeInsulatorMedium

Bases: AbstractChargeMedium

Insulating medium. Conduction simulations will not solve for electric potential in a structure that has a medium with this charge.

Parameters:

• name (Optional[str] = None) – Optional unique name for medium.

• frequency_range (Optional[tuple[float, float]] = None) – [units = (Hz, Hz)]. Optional range of validity for the medium.

• allow_gain (bool = False) – Allow the medium to be active. Caution: simulations with a gain medium are unstable, and are likely to diverge.Simulations where allow_gain is set to True will still be charged even if diverged. Monitor data up to the divergence point will still be returned and can be useful in some cases.

• nonlinear_spec (Optional[Union[NonlinearSpec, NonlinearSusceptibility]] = None) – Nonlinear spec applied on top of the base medium properties.

• modulation_spec (Optional[ModulationSpec] = None) – Modulation spec applied on top of the base medium properties.

• viz_spec (Optional[VisualizationSpec] = None) – Plotting specification for visualizing medium.

• heat_spec (Optional[Union[FluidSpec, SolidSpec, SolidMedium, FluidMedium]] = None) – DEPRECATED: Use MultiPhysicsMedium. Specification of the medium heat properties. They are used for solving the heat equation via the HeatSimulation interface. Such simulations can beused for investigating the influence of heat propagation on the properties of optical systems. Once the temperature distribution in the system is found using HeatSimulation object, Simulation.perturbed_mediums_copy() can be used to convert mediums with perturbation models defined into spatially dependent custom mediums. Otherwise, the heat_spec does not directly affect the running of an optical Simulation.

• permittivity (float = 1.0) – [units = None (relative permittivity)]. Relative permittivity.

Example

>>> import tidy3d as td
>>> solid = td.ChargeInsulatorMedium()
>>> solid2 = td.ChargeInsulatorMedium(permittivity=1.1)

Note

A relative permittivity \(\varepsilon\) will be assumed 1 if no value is specified.
