Metamaterials are materials that are man-made with special characteristics that are not found naturally. Meta things act in a way that has not been even dreamt of possible concerning manipulation of the electromagnetic waves in metamaterials, as long as their structure is altered at the micro or nanoscale. These properties have made metamaterials an innovative field in other related areas such as optics, and telecommunication those in material science.

A negative refractive index is one of the most outstanding features associated with the use of metamaterials. This property lets them refract light and other electromagnetic waves in the opposite way to usual material with a prospect of apologized for super lenses. In contrast with traditional lenses that are inherently restricted by diffraction, sub-wavelength imaging material lenses the metamaterials used can focus the light beyond the wavelength hence creating additional possibilities in imaging, microscopy, and in the medical diagnosis field.

One of the other promising prospective applications of metamaterials is cloak technology. Metamaterials involve manipulation of the interaction of light and electromagnetic waves, enabling certain objects to be rendered invisible or invisible or equally invisible to specific radiation forms. Yet this idea remains mostly theoretical, despite the recent research done, and may have uses in defense and stealth industries.

Metamaterials play also an important role in the development of nanophotonics and waveguides which it is able to guide light through the nanostructures with better efficiency than the conventional materials. Due to their control characteristics of waves, they are suitable for the third generation of telecommunication and data transfer where control of light and electromagnetic is paramount for speed and frequency.

In energy applications, metamaterials are being utilized to increase the efficiency of solar energy collection and increase the effectiveness of optoelectronic tools and gadgets. Further studies into metamaterials may well change such fields as health care, electronics, aerospace industry, and defense as they offer a new level of control over actual processes.
