## Cartesian coordinate system

n.
A coordinate system in which the coordinates of a point are its distances from a set of perpendicular lines that intersect at an origin, such as two lines in a plane or three in space.

## Car·te·sian coordinate system

(kär-tē′zhən)
A system in which the location of a point is given by coordinates that represent its distances from perpendicular lines that intersect at a point called the origin. A Cartesian coordinate system in a plane has two perpendicular lines (the x-axis and y-axis); in three-dimensional space, it has three (the x-axis, y-axis, and z-axis).

The contour map (xy plane) of flow fronts is given in Fig.

The effect is more visible on the headset antenna due to the presence of body mass both at side (i.e., head) and underneath (i.e., shoulder) decreasing its radiation in both directions in XY plane. Effect of the head is dominant in YZ plane reducing its radiation between 0-90 degrees.
Z axis will be perpendicular on XY plane and will intersect the X axis at the middle of the distance between the extreme limits of the longitudinal sliding elements, and the origin point of the machine's reference system, O, will be found at the intersection of Z axis with XY plane.
The achieved beam width is of approximately 25[degrees] and 27[degrees] in XY plane ([theta] = 90[degrees]) and approximately 51[degrees] and 54[degrees] in YZ plane ([phi] = 90[degrees]) for prototypes I and II, respectively.
Figures 2(a)-2(d) show the magnetic field distribution for the lossless cloak, the lossy cloak, the bare PEC octahedron and the equivalent PEC octahedron in virtual space in an xy plane (z = 0 m) respectively, when an Hz polarized plane wave is incident along [??] direction.
X-axis is parallel to the flight path of the platform, Y-axis is parallel to the cross-track dimensional sparse linear array, Z-axis is perpendicular to the XY plane, the origin of the coordinate O is the center of the three dimensional imaging scene (O is also used as the reference point for dechirp signal processing).
However, the direction of peak radiation has changed from the xy plane to an angle elevated from that plane.

The scattered fields are measured in the xy plane ([theta] = [pi]/2).
In the K03 station (Barika Au-index), Rxy=1.29 and Ryz=2.43 and the total finite strain ratio equal to 2.05, the foliated plane (XY plane) developed on the D1 phase superimposed by stretching lineation in D2.
In addition, Alio explained, despite hexapods exhibiting good stiffness compared to serial stacked multi-axis systems, this is really only in the vertical z axis, with weaknesses in the xy plane.
