tidy3d.plugins.smatrix.ports.base_lumped.AbstractLumpedPort#

class AbstractLumpedPort[source]#

Bases: AbstractTerminalPort

Class representing a single lumped port.

Parameters:

  • name (str) – Unique name for the port.

  • impedance (complex = 50) – [units = ohm]. Reference port impedance for scattering parameter computation.

  • num_grid_cells (Optional[PositiveInt] = 3) – Number of mesh grid cells associated with the port along each direction, which are added through automatic mesh refinement. A value of None will turn off automatic mesh refinement.

  • enable_snapping_points (bool = True) – When enabled, snapping points are automatically generated to snap grids to key geometric features of the lumped port for more accurate modelling.

Attributes

Methods

snapped_center(grid)

Get the exact center of this port after snapping along the injection axis.

to_current_monitor(freqs[, snap_center, grid])

Field monitor to compute port current.

to_monitors(freqs[, snap_center, grid])

Field monitors to compute port voltage and current.

to_voltage_monitor(freqs[, snap_center, grid])

Field monitor to compute port voltage.

snapped_center(grid)[source]#

Get the exact center of this port after snapping along the injection axis. Ports are snapped to the nearest Yee cell boundary to match the exact position of the load.

abstract property to_load#

Create a load from the lumped port.

abstract to_voltage_monitor(freqs, snap_center=None, grid=None)[source]#

Field monitor to compute port voltage.

abstract to_current_monitor(freqs, snap_center=None, grid=None)[source]#

Field monitor to compute port current.

to_monitors(freqs, snap_center=None, grid=None, **kwargs)[source]#

Field monitors to compute port voltage and current.
