Metamaterials are structures that are purposefully constructed and have distinctive characteristics. They are designed to reach negative values of permittivity and permeability simultaneously in a certain frequency range. This results in negative values of the index of refraction. Because of how sensitive the resonant frequencies of these structures are to the geometry of the structure itself, they are often used in the functioning of the structures themselves. Cloaking, super lenses, sub-diffraction focusing, perfect absorption, and biosensing are only a few of the various frequency ranges in which metamaterials have been proven. Cloaking, super lenses, and perfect absorption have also been demonstrated. These range anywhere from gigahertz to optical frequencies. Split-ring resonators, also known as SRRs, are an essential construction block since they are one of the core components that are required to really create metamaterials. As SRRs, either thin metallic rings or split square loops are employed, and they are both positioned on top of a dielectric substrate. SRRs are some of the earliest metamaterial-based microwave resonators. This is due to the fact that their geometries are much smaller than the wavelength of the electromagnetic waves that are stimulating them.
