The prefix meta (from the Greek word ‘beyond’) denotes that the material’s properties go beyond what we perceive in nature. Metamaterials are a new type of functional material based on micro- and nanoscale patterns or structures that cause them to interact with light and other types of energy in ways not seen in nature.
Internal micro- and nanostructures, rather than the chemical composition present in natural materials, give these intentionally manufactured composite materials their features. As a result, metamaterial structures provide traits and capabilities that are difficult to achieve using traditional material discovery or chemical manufacturing techniques.
Metamaterials are usually made up of several identical elements made of common materials like metals or nonconductive materials.
The India Metamaterial Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2026, registering a CAGR of XX% from 2024 to 2030.
“Textile-based metamaterials for radar absorption” developed by IIT-Kanpur researchers can be utilised as uniforms for soldiers and skirtings or covers for ground vehicles. In other words, these textile-based metamaterials can help soldiers and armoured vehicles dodge adversary radar, motion-detecting ground sensors, and thermal imaging systems.
For vehicle windshields or the canopy of slow aeroplanes, transparent metamaterial absorbers have been created.
Origami metamaterials, created by the Indian Institute of Technology Madras, could have a wide range of applications. These mix the Japanese art of paper folding (origami) with an existing material and fold it to achieve the desired qualities.
Optical filtering, medical devices, remote aeronautical operations, sensor detectors, solar power management, crowd control, radomes, antenna lenses, and even earthquake protection are all possible applications of Metamaterials.
Metamaterial lenses may even be able to image below the diffraction limit, which precludes traditional optical lenses from magnifying any farther.
