Interactive Device for the Selective Control of Electromagnetic Radiation

摘要

The present invention relates to the technical field of systems for the polarisation of electromagnetic radiation, particularly light radiation, and more particularly solar radiation. The present invention also relates to the application of such systems to the dynamic screening of essentially transparent surfaces, particularly in the building construction, automotive, architecture and interior design sectors and other sectors that require such screening.

主权项

1. A transparent multilayer device, comprising two polarisers comprising a grid of nano-wire filaments, said polarisers being arranged in succession along a path of the direction of propagation of electromagnetic radiation and being capable of linear translatory movement relative to one another, wherein the pitch between the filaments is constant and less than 390 nm and the filaments occupy an essentially constant space between 2.5% and 50% of the pitch and are organized in parallel bands of regular shape, wherein the bands are of the same dimensions but have different orientations of a polarisation axis, and wherein the polarisation axis of each band is rotated with respect to adjacent bands, and through constant angles selected in the range between tenths of a degree and 45 degrees.
