Focusing systems based on two-dimensional photonic crystals
Methods of focusing electromagnetic waves based on the use of two-dimensional photonic crystals formed by metal and dielectric elements are considered. In the first case the physical basis for the creation of radiation focusing systems consists in the manifestation of the properties of a homogeneous medium with ultra-low refractive index by metal photonic crystals at the frequencies of the first allowed zone. In the second case the possibility of constructive interference of direct transmission waves and edge waves diffracting at the edges of spatially bounded dielectric structures is used for focusing.
