    Types of Grids and Surfaces
    Wire grids can be composed of curved or straight wires and can be used to model grids and approximate conductive surfaces. The wires of a grid do not overlap but are connected to each other...
    Attributes of Grids and Surfaces
    The Attributes tab in the Draw dialog box allows you to define how a geometric shape (like a Plate, Disc, or Sphere) is mathematically represented in the simulation. While the shapes differ, they all share the same attribute logic. Defining the Structure: Wire Grid vs. Solid Surface The most critical choice is made in the […]
    Modifying a Grid or Surface
    In AN-SOF, wire grids and solid surfaces are treated as collections of individual wires or strips. Once created, they cannot be re-opened in the original “Draw” dialog box. Instead, you use Massive Edition tools to adjust the entire structure at once. Selecting the Structure To modify a grid or surface, you must first select the […]

    Adding Wire Grids and Solid Surfaces
    These articles describe the different grid and surface types and provide guidance on how to add them in the AN-SOF workspace.
    Patch
    The Patch refers to a rectangular patch on the xy-plane composed of wires having a flat or rectangular cross-section. Use this wire grid to model patch and microstrip antennas...
    Plate
    The Plate refers to a plate or bilinear surface. Go to Draw > Wire Grid > Plate in the main menu to display the Draw dialog box for the Plate...
    Disk
    The Disc refers to a disc or circular surface. Go to Draw > Wire Grid > Disc in the main menu to display the Draw dialog box for the Disc...
    Flat Ring
    The Flat Ring refers to a disc with a hole at its center. Go to Draw > Wire Grid > Flat Ring in the main menu to display the Draw dialog box for the Flat Ring...
    Cone
    Go to Draw > Wire Grid > Cone in the main menu to display the Draw dialog box for the Cone. There are three pages: Cone, Attributes and Materials.
    Truncated Cone
    Go to Draw > Wire Grid > Truncated Cone in the main menu to display the Draw dialog box for the Truncated Cone. There are three pages: Truncated Cone, Attributes and Materials.
    Cylinder
    Go to Draw > Wire Grid > Cylinder in the main menu to display the Draw dialog box for the Cylinder. There are three pages: Cylinder, Attributes and Materials.
    Sphere
    Go to Draw > Wire Grid > Sphere in the main menu to display the Draw dialog box for the Sphere. There are three pages: Sphere, Attributes and Materials.
    Paraboloid
    Go to Draw > Wire Grid > Paraboloid in the main menu to display the Draw dialog box for the Paraboloid. There are three pages: Paraboloid, Attributes and Materials.
