    Syntax

    p2D = slice(pcbobj)
    p2D = slice(pcbobj,p1, p2)

    Description

    p2D = slice(pcbobj) returns pcb2D object by taking 2-D cross section through all layers of pcbComponent object in the Y-Z plane at x = 0, capturing all layers.

    example

    p2D = slice(pcbobj,p1, p2) returns pcb2D object by taking 2-D cross section through all layers of pcbComponent object at slicing axis defined by two end points p1 and p2.

    Create pcbComponent object from rfpcb catalog object - in this example a coupled microstripline filter catalog object is used. Note that solver type must be specified MoM for slice function and 2-D solver to function.

    cfilter = pcbComponent(coupledMicrostripLine(Conductor=metal('copper')))
    cfilter = 
  pcbComponent with properties:

              Name: 'Coupled Line Filter'

    Use slice function on pcbComponent to create pcb2D object. Visualize object, which has two signal traces in this case. All signal traces must be specified within a single cell. Note that the 2-D field solver's coordinate axes convention differs from the convention used for 3-D PCB structures: The y-axis runs in a vertical direction through layers of the 2D structure, with y=0 corresponding to the bottom of the PCB structure; the x-axis runs perpendicular to the y-axis and direction of signal propagation.

    pcb2d = slice(cfilter)
    pcb2d = 
  pcb2D with properties:

           Name: 'MyPCB2D'
     BoardWidth: 0.0300
    BoardCenter: 0
         Layers: {[1×2 trace2D]  [1×1 dielectric]  [1×1 trace2D]}

    Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 6 objects of type patch, text. These objects represent Teflon, Ground, Signal.

    Calculate s parameters and RLGC properties at 1.9 GHz.

    Input Arguments

    collapse all

    Input specified as pcbComponent object.

    Example: pcbobj = pcbComponent(coupledMicrostripLine(Conductor=metal('copper')))

    Data Types: string

    Name-Value Arguments

    collapse all

    Example: [-0.02 0.004]

    Specify optional pairs of arguments as Name1=Value1,...,NameN=ValueN, where Name is the argument name and Value is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

    x1, y1 coordinates of the first cut line end point specified in meters.

    Example: [-0.02 0.004] places end point at coordinates x1 = -0.02, y1 = 0.004 meters.

    Data Types: double

    x2, y2 coordinates of second cut line end point, specified in meters.

    Example: [0.02 0.004] places end point at coordinates x2 = 0.02, y2 = 0.004 meters.

    Data Types: double

    Output Arguments
