Optical properties of metamaterials based on porous channel photonic structures and applications for optical DEVICES

摘要

Optical properties of a new kind of metamaterials based on hierarchically organized mirror channels with semitransparent walls, metamirror structures (MMS) are considered. Despite the difference in physical mechanisms, some properties of MMS i.e. transmission and reflection are close to that exhibited by left-handed materials. The ray tracing is considered for different MMS geometries and types. It is shown that one-step reflective 2D MMS based on rectangular elementary cells being properly curved possess lens properties and MMS lens generalized law is derived. Properties of a mirror lens prototype with the finite meta-focus position made from one layer 2D MMS with reflecting walls are evaluated theoretically and experimentally. Micro-machine mirror systems and modified macroporous structures are discussed as mirror lens devices.
