GroundExposed

class pmrf.models.composite.nodal.GroundExposed(exposed: Model, *, z0: complex = 50 + 0j, name: str | None = None, metadata: Any = None)

Bases: Model

A wrapper that converts an N-port grounded model into an (N+1)-port model by exposing the global ground as a single, accessible terminal.

The original signal ports remain at indices 0 to N-1. The new exposed ground port is at index N.

Parameters:

• exposed (Model) – The inner N-port model whose ground is to be exposed.

• Reference

• ----------------------

• of (Uses the Indefinite Admittance Matrix (IAM) transformation. Because the sum)

• zero (currents entering a subcircuit must be)

• calculated (the exposed global node is)

• zero. (so that the rows and columns of the expanded Y-matrix sum to)

exposed: Model

The inner N-port model to be wrapped.
