tidy3d.SteadyCapacitanceData#

class SteadyCapacitanceData[source]#

Bases: HeatChargeMonitorData

Class that stores capacitance data from a Charge simulation.

Parameters:

attrs (dict = {}) – Dictionary storing arbitrary metadata for a Tidy3D object. This dictionary can be freely used by the user for storing data without affecting the operation of Tidy3D as it is not used internally. Note that, unlike regular Tidy3D fields, attrs are mutable. For example, the following is allowed for setting an attr obj.attrs['foo'] = bar. Also note that Tidy3D` will raise a TypeError if attrs contain objects that can not be serialized. One can check if attrs are serializable by calling obj.json().
monitor (SteadyCapacitanceMonitor) – Capacitance data associated with a Charge simulation.
symmetry (Tuple[Literal[0, 1], Literal[0, 1], Literal[0, 1]] = (0, 0, 0)) – Symmetry of the original simulation in x, y, and z.
symmetry_center (Tuple[float, float, float] = (0, 0, 0)) – Symmetry center of the original simulation in x, y, and z.
hole_capacitance (Optional[SteadyVoltageDataArray] = None) – Small signal capacitance ($frac{dQ_p}{dV}$) associated to the monitor.
electron_capacitance (Optional[SteadyVoltageDataArray] = None) – Small signal capacitance ($frac{dQn}{dV}$) associated to the monitor.

Notes

The small signal-capacitance of electrons $C_n$ and holes $C_p$ is computed from the charge due to: electrons $Q_n$ and holes $Q_p$ at an applied voltage $V$ at a voltage difference

$\Delta V$ between two simulations.

\[C_{n,p} = \frac{Q_{n,p}(V + \Delta V) - Q_{n,p}(V)}{\Delta V}\]

This is only computed when a voltage source with more than two sources is included within the simulation and determines the $\Delta V$.
