A photonic metamaterial (PM), also known as an optical metamaterial, is a type of electromagnetic metamaterial, that interacts with light, covering terahertz (THz), infrared (IR) or visible wavelengths. The materials employ a periodic, cellular structure. The subwavelength periodicity distinguishes photonic … See more While researching whether or not matter interacts with the magnetic component of light, Victor Veselago (1967) envisioned the possibility of refraction with a negative sign, according to Maxwell's equations. A refractive index with … See more Natural materials, such as precious metals, can achieve ε < 0 up to the visible frequencies. However, at terahertz, infrared and visible … See more An effective (transmission) medium approximation describes material slabs that, when reacting to an external excitation, … See more Optical wavelengths are much shorter than microwaves, making subwavelength optical metamaterials more difficult to realize. Microwave … See more Photonic metamaterial SRRs have reached scales below 100 nanometers, using electron beam and nanolithography.
