In this paper a new concept of designing Fresnel lens concentrators on the basis of magnetic microwires with a complex spatial distribution of their density is proposed. The optical properties of microwires are analyzed in terms of their scattering indicatrix, and the design of the lens in the form of a sandwich consisting of two discs with concentric rings with current running inside and the microwires confined in between the discs is discussed. It is shown that such a design allows one to ensure the configuration of a complex spatial distribution of microwires and their effective control by changing the currents in the system. A comparative analysis is performed for microwires with diamagnetic, paramagnetic and ferromagnetic core. |
