    Description

    Use pcb2D to create a 2-D cross section model of a transmission line for use with the 2-D solver.

    Creation

    Syntax

    pcb2d = pcb2D
    pcb2d = pcb2D(PropertyName=Value)
    S = sparamaters(pcb2d,freq,LineLength=0.5)

    Description

    pcb2d = pcb2D returns a default 2-D cross section of a microstripline represented by two metal layers with a Teflon substrate in between.

    example

    pcb2d = pcb2D(PropertyName=Value) sets Properties of a 2-D cross section of a microstripline using one or more name-value arguments. Properties not specified retain their default values.

    S = sparamaters(pcb2d,freq,LineLength=0.5) calculates the s parameters of 2D cross section of microstripline at a specified frequency and line length.

    PCB cross section name specified as a string or character vector.

    Example: "csname"

    Data Types: string

    Cross section width, specified as a scalar in meters.

    Example: 0.0550

    Data Types: double

    X-axis coordinate center of the PCB cross section, specified as a scalar in meters.

    Example: 0.0010

    Data Types: double

    Metal and dielectric layers in cross section, specified as a cell array, and ordered from top layer to bottom layer.

    Note

    If one of the cells includes multiple PCB trace objects, the pcb2d object constructs those traces on the same board layer.

    Data Types: cell
