Overview
Researchers have created meta materials that can manipulate electromagnetic waves, such as microwaves and infrared radiation. The properties of meta materials are highly dependent on their internal structure, which can be tailored to achieve specific benefits. A meta material with a negative refractive index can be used to create a cloaking device that bends light around an object, making it invisible.
🎵 Origins & History
Origins paragraph — The concept of meta materials is reportedly being explored by researchers. However, the information available on the origins of meta materials is limited.
⚙️ How It Works
How it works — Meta materials are created by arranging multiple materials, such as metals and plastics, in repeating patterns at scales smaller than the wavelengths of the phenomena they influence. This deliberate design allows meta materials to manipulate electromagnetic, acoustic, or seismic waves, giving them properties that are rare or absent in naturally occurring materials. For example, researchers have developed meta materials that can absorb electromagnetic radiation.
