We are living in the era of science and technology. Each and every day we come through various inventions. Going a step ahead, scientist has invented electronic applications such as a three-dimensional electron lens and electronic invisibility devices.
The researchers are using Weyl metamaterials, a generalization of Weyl semimetals that has the capacity to enable new types of electronic devices through geometry engineering process. It offers a route to make the charge carriers move providing a tabletop laboratory for simulating curved-space quantum physics and specific cosmological incident. These charge carriers behave like massless particles that are moving at the speed of light. It reflects the special theory of relativity of Einstein. This experiment has opened the new way to fundamentally new electronics applications, such as the developing of electronic invisibility devices that can be possible after this stage. An artificially developed curved geometry, which bends the motion of charge carriers in a much managed manner, is the key idea behind this potential future application. It is going to bring a revolution to achieve a similar functionality in electronic systems. In this functionality of optical invisibility equipment, it has been found that the ray of light bypasses through a hidden object. The theory is based on the theory of curved-space geometry.
