# Wire

### From openEMS

## Description

Define a cylinder-like wire by its coordinate arrays and radius.

CSX = AddWire(CSX, propName, prio, points, wire_rad, varargin)

with the parameters

**CSX**: The original CSX structure**propName**: name of the assigned property**prio**: priority of the primitive**points**: two-dimensional coordinates of the base polygon- array column refers to point number
- array row refers to its x,y,z- position:

points(1,point_number): position-x of 'point_number'.

points(2,point_number): position-y of 'point_number'.

points(3,point_number): position-z of 'point_number'.

**wire_rad**: wire radius**varargin**: a key/value list of primitives variable arguments

### Example

This example creates a Biquad antenna from wire of radius 0.1 on xz-plane, with length of each side=.

points(1,1) = 0;points(2,1) = 0;points(3,1) = 0; points(1,2) = 5;points(2,2) = 0;points(3,2) = 5; points(1,3) = 10;points(2,3) = 0;points(3,3) = 0.5; points(1,4) = 15;points(2,4) = 0;points(3,4) = 5; points(1,5) = 20;points(2,5) = 0;points(3,5) = 0; points(1,6) = 15;points(2,6) = 0;points(3,6) = -5; points(1,7) = 10;points(2,7) = 0;points(3,7) = -0.1; points(1,8) = 5;points(2,8) = 0;points(3,8) = -5; points(1,9) = 0;points(2,9) = 0;points(3,9) = 0; CSX = AddMetal(CSX,'metal'); CSX = AddWire(CSX,'metal',10, points,0.1);
