tidy3d.components.microwave.data.dataset.TransmissionLineDataset

class TransmissionLineDataset

Bases: ModeFreqDataset

Holds mode data that is specific to transmission lines in microwave and RF applications, like characteristic impedance.

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().

• Z0 (ImpedanceFreqModeDataArray) – The characteristic impedance of the transmission line.

• voltage_coeffs (VoltageFreqModeDataArray) – Quantity calculated for transmission lines, which associates a voltage-like quantity with each mode profile that scales linearly with the complex-valued mode amplitude.

• current_coeffs (CurrentFreqModeDataArray) – Quantity calculated for transmission lines, which associates a current-like quantity with each mode profile that scales linearly with the complex-valued mode amplitude.

Notes

The data in this class is only calculated when a MicrowaveModeSpec is provided to the ModeMonitor, ModeSolverMonitor, ModeSolver, or ModeSimulation.
