In recent years, the creation of invisibility technology has become increasingly of interest to the scientific community. There are a lot of theories and even prototypes in the creation of invisible materials. But, according to the editorial office of EurikAlert, a group of researchers from the University of Extremadura (Spain) has recently been able to demonstrate the technology of electromagnetic masking of objects based on the refractive properties of some substances.
Now the main existing technologies for creating invisibility are based on the fact that the object needs to be covered with a special substance. Spanish scientists also propose to initially add special additives to the parts and materials of the required structures.
“Most of the methods by which invisibility cloaks are developed use special properties of some materials that allow light to bend around an object, making it invisible. We used another technique called plasma masking, which makes invisible not only the covering material, but the object itself. The effect of electromagnetic invisibility is achieved by filling structures with special materials with high dielectric and magnetic properties.”- said one of the authors of Professor Alberto Serna.
Thus, the new method allows to achieve the invisibility of the object without the use of any external influences. In addition, invisibility with fillers allows an object to interact with its environment without interference from external masking. At the moment, the technique is applicable only for small objects, but the authors believe that in the future it can be improved in order to apply to more massive structures.
