- class CapNInterdigital(design: QDesign, name: str = None, options: Dict = None, make=True, component_template: Dict = None)[source]¶
Generates a two pin (+) structure comprised of a north CPW transmission line, and a south transmission line, coupled together via a finger capacitor. Such a structure can be used, as an example, for generating CPW resonators. (0,0) represents the center position of the component. Setting finger length to 0 gives a simple gap capacitor. The width of the gap capacitor is found via.
(cap_width * finger_count + * cap_gap * (finger_count-1)).
Inherits QComponent class.

north_width: ‘10um’ – The width of the ‘north’ portion of the CPW transmission line
north_gap: ‘6um’ – The dielectric gap of the ‘north’ portion of the CPW transmission line
south_width: ‘10um’ – The width of the ‘south’ portion of the CPW transmission line
- south_gap: ‘6um’ – The dielectric gap of the ‘south’ portion of the CPW transmission line
(also for the capacitor gap to ground)
cap_width: ‘10um’ – The width of the finger capacitor metal (and islands)
cap_gap: ‘6um’ – The width of dielectric for the capacitive coupling/fingers
cap_gap_ground: ‘6um’ – Width of the dielectric between the capacitor and ground
finger_length: ‘20um’ – The depth of the finger islands of the capacitor
finger_count: ‘5’ – Number of fingers in the capacitor
cap_distance: ‘50um’ – Distance of the north point of the capacitor from the north pin
Create a new Metal component and adds it’s default_options to the design.
design (QDesign) – The parent design.
name (str) – Name of the component. Auto-named if possible.
options (dict) – User options that will override the defaults. Defaults to None.
make (bool) – True if the make function should be called at the end of the init. Options be used in the make function to create the geometry. Defaults to True.
component_template (dict) – User can overwrite the template options for the component that will be stored in the design, in design.template, and used every time a new component is instantiated. Defaults to None.
ValueError – User supplied design isn’t a QDesign
- Note: Information copied from QDesign class.
self._design.overwrite_enabled (bool): When True - If the string name, used for component, already exists in the design, the existing component will be deleted from design, and new component will be generated with the same name and newly generated component_id, and then added to design.
When False - If the string name, used for component, already exists in the design, the existing component will be kept in the design, and current component will not be generated, nor will be added to the design. The variable design.self.status will still be NotBuilt, as opposed to Initialization Successful.
Either True or False - If string name, used for component, is NOT being used in the design, a component will be generated and added to design using the name.
the full module name with the class name.

Interface for components to get pin data.
Creates template options for the Metal Component class required for the class to function, based on the design template; i.e., be created, made, and rendered.
Build the component.
Parse the options, converting string into interpreted values.
Parse a string, mappable (dict, Dict), iterable (list, tuple) to account for units conversion, some basic arithmetic, and design variables.
Use the element_handler to get a list of all the table names used in QGeometry.
Fetched the component bound dict_value.
Returns a dict of element qgeometry (shapely geometry) of the component as a python dict, where the dict keys are the names of the qgeometry and the corresponding values are the shapely geometries.
Returns a list of element qgeometry (shapely geometry) of the component as a python list of shapely geometries.
