WitrynaAfter reviewing the requirements, which have to be satisfied by a metamaterial-based subwavelength imaging system, a thin film lens is reported herein. The material of the lens is a composite of spherical Ag nanoparticles embedded in SiO2 host material. The image of the lens is calculated by solving Maxwell equations with the transfer matrix … WitrynaLenses made of metamaterials may even enable imaging below the diffraction limit that prevents conventional optical lenses from magnifying any further. Gradient-index metamaterials can even provide a kind of “invisibility” based on these optical applications. Further Reading: Developing a Highly Configurable Metamaterial with …
