shape.OpenBox

Create open box centered at origin

Since R2023b

Description

The shape.OpenBox lets you create an open box with metal and dielectric material properties centered at the origin. Use this open box along with the other shapes and the geometric operations to create a shape for the custom antenna.

Creation

Syntax

openbox = shape.OpenBox

openbox = shape.Box(Name=Value)

Description

openbox = shape.OpenBox creates a box with one open face, centered at the origin.

openbox = shape.Box(Name=Value) sets additional Properties using one or more name-value arguments. Name is the property name and Value is the corresponding value. You can specify several name-value arguments in any order as Name1=Value1, ..., NameN=ValueN. Properties that you do not specify retain their default values.

Properties

Name — Open box name

"myOpenBox" (default) | string

Open box name, specified as a string.

Example: "OpenBox1"

Data Types: string

Center — Open box center point

[0 0 0] (default) | three-element real vector

Open box center point, specified as a three-element vector of Cartesian coordinates in meters.

Example: [1 1 1]

Data Types: double

Length — Length of open box

1 (default) | positive scalar

Length of the open box along the x-axis, specified as a scalar in meters.

Example: 2

Data Types: double

Width — Width of open box

2 (default) | positive scalar

Width of the open box along the y-axis, specified as a scalar in meters.

Example: 4

Data Types: double

Height — Height of box

2 (default) | positive scalar

Height of the box along the z-axis, specified as a scalar in meters.

Example: 4

Data Types: double

Metal — Metal material of shape

"PEC" (default) | string

Metal material of the shape, specified as a metal name string from the Metal Catalog.

Example: "Copper"

Data Types: string

Dielectric — Dielectric material of shape

"Air" (default) | string

Dielectric material of the shape, specified as a dielectric name string from the Dielectric Catalog.

Example: "Teflon"

Data Types: string

Color — Color of shape

"y" (default) | character scalar | "Individual" | three-element real vector of RGB triplet

Color of shape, specified as either a character for color short name or a three-element real vector of RGB triplets. The default shape color is yellow. See the Types of Color Values supported by this property. When you unite two shapes of different colors, use "Individual" value to retain the colors of the original shapes in the resultant shape.

Example: "r"

Example: [0 0.447 0.741]

Data Types: double | string | char

Transparency — Transparency of shape

1 (default) | positive scalar within (0,1)

Transparency of shape, specified as a scalar in the (0,1) range, where 0 corresponds to full transparency while 1 corresponds to full opaqueness.

Example: 0.75

Data Types: double

EdgeColor — Color of shape edges

"k" (default) | character scalar | "Individual" | three-element real vector of RGB triplet

Color of shape edges, specified as either a character for color short name or a three-element real vector of RGB triplets. The default edge color is black. See the Types of Color Values supported by this property. When you unite two shapes of different edge colors, use "Individual" value to retain the edge colors of the original shapes in the resultant shape.

Example: "b"

Example: [0.4940 0.1840 0.5560]

Data Types: double | string | char

Examples

Create and Mesh Open Box

Create a 2 cm x 2 cm x 2cm open box. Rotate it by 45 degrees around the z-axis.

r = shape.OpenBox(Length=0.02,Width=0.02,Height=0.02);
rotateZ(r,45);

Mesh it with a maximum edge length of 5 mm.

mesh(r,MaxEdgeLength=5e-3)
