class kqcircuits.simulations.port.Port(number: int, resistance: float = 50, reactance: float = 0, inductance: float = 0, capacitance: float = 0, face: int = 0, junction: bool = False)

Bases: object

Base data structure for simulation ports.

Depending on your simulation type, these produce excitations, set potentials, or act as ideal RLC lumped elements.

Parameters

• number – Port number.

• resistance – Real part of impedance. Given in Ohms (\(\Omega\)).

• reactance – Imaginary part of impedance. Given in Ohms (\(\Omega\)).

• inductance – Inductance of the element. Given in Henrys (\(\text{H}\)).

• capacitance – Capacitance of the element. Given in Farads (\(\text{F}\)).

• face – Integer-valued face index for the port.

• junction – Whether this port models a SQUID/Junction. Used in EPR calculations.

as_dict()

Returns attributes as a dictionary.
