Various coating methods are used in the development of organic textures. The MALDI method is one of the most important one amongst the others. Three-axis robotic spraying devices are frequently used in tissue engineering. The inboard joints of the robot manipulator are designed with prismatic joints. The last two joints are designed with two revolute joints which are composed of a two-axes spherical wrist. With this design, complex surfaces can be reached with any orientation angle.

Metamaterials are man-made artificial materials that are not a natural material but rather have different electromagnetic properties. One of the features mostly studied in recent years is that it nearly absorbs all incoming electromagnetic waves. These features make it possible to invisibility against remote sensing systems. Thus, the radar cross-section area (RCA) representing the radar visibility can be reduced by covering the target plane with metamaterial. As a first step in this work, the unit cell of the metamaterial, which has a resonance effect, is designed to achieve high absorption at 6.0 GHz. Then, using the unit cell's scalability feature for this metamaterial, two more-unit cells with resonance effect at 5.0 GHz and 7.0 GHz were designed, respectively. Subsequently, all three were brought next to each other and super-cell structure was introduced. The structure obtained shows 94.62% absorption at 5.08 GHz, 99.95% absorption at 5.98 GHz and 90.42% absorption at 7.02 GHz, respectively, in the C band region (4-8 GHz).
