AbstractStriplineFormulation

class pmrf.models.components.lines.stripline.AbstractStriplineFormulation

Bases: Module

Abstract base class for a closed-form stripline formulation.

Homogeneous filling gives $

arepsilon_e= arepsilon_r$ without modal

dispersion.

abstractmethod quasi_static(*, w, b, t, ep_r) → PlanarQuasiStaticResult

Calculate the quasi-static solution.

Parameters:

• w (ArrayLike) – Width of the centre strip in meters.

• b (ArrayLike) – Ground-plane separation in meters.

• t (ArrayLike | None) – Thickness of the strip in meters, or None for a zero-thickness strip.

• ep_r (jnp.ndarray) – Complex relative permittivity of the filling, shape (npoints,).

Returns:

The effective permittivity, impedance and effective width.

Return type:

PlanarQuasiStaticResult
