Defines the geometry of the electromagnetic simulation.
LayoutView of the component to simulate
Bounding box of the simulation. Default is [None, None, None]. [None, None, (-2.0, 10.0)] means to derive x and y span from the component, but use (-2.0, 10.0) in the z-direction (out-of-plane).
List of layers that need to be excluded. Default is not to exclude any layer.
List of layers that need to be virtually fabricated. By default all layers used in the layout are virtually fabricated. Setting this overrides the behavior of ‘excluded_layers’
The process flow used for virtual fabrication. By default use TECH.VFABRICATION.PROCESS_FLOW. Can be changed to customize the process flow, in order to simulate various changes to the process.
waveguide_growth: float and Real, number and number >= 0, optional
Distance to grow the waveguides at their unconnected ports.
