| Summary: | Metamaterials have emerged as a revolutionary class of materials in the field of photonics, offering unprecedented unparalleled control over the modification and propagation of light. These engineered materials derive their unique optical properties from their meticulously designed subwavelength structures rather than their chemical composition. Metamaterials enable several advanced functionalities, such as negative refractive indices for superlensing, which allows imaging beyond the diffraction limit. Tuned permittivity refers to the deliberate modification of a material's ability to interact with electric fields, typically achieved through precise engineering at the nanoscale. By adjusting the dimensions, composition and arrangement of nanoscale structures within the metamaterials researchers can tailor its permittivity across different frequencies and polarisation states. This capability enables advanced functionalities such as enhanced light-matter interactions, improved optical sensing, and the development of novel electromagnetic devices. |
