Meta-material Based Novel Stealth Surface

Stealth technology has been a topic of concern for a long time in the military target, which can not only enhance the viability of our forces but also can improve the deterrent for the enemy. With the rapid development of the technology, the invisible technology is no longer limited to the traditional invisible mode, and there are many kinds of new invisible technology implements, such as the cloak, the carpet, etc. These new technologies, achieved through the implementation of meta-material, are based on the principle of the transformation optics.However, the closed form of invisible technology,which makes the targets invisible by enwrapping them, will be costly when the shapes of the targets are enormous or irregular. This paper, therefore, basing on the open structure, brings out a new mode of stealth. Through using the defuse reflection in free space, this technology stimulates the randomly undulating grounds and covers the RCS of things placed on the surface.Main contents and contributions of the thesis are lifted ad follows:1. Theoretical introductions and simulations of miscible technology are mentioned.2. This paper makes simulations about Bistatic Radar Cross-sections of different shapes and sizes and camouflages the kind of physical structure with strong scattering we come up with by using different undulated heights. Then we design the meta-material surface with the method of making scramb led background to hide the targets and optimize it to make it more compact and slimmer.3. Based on the effect media theory, the patch shapes and perforated design are ordered out to implement the stealth meta-surface.The simulation results demonstrate that, the validity of our proposed design.
