RADIATION DISSIPATING DEVICE Russian patent published in 2005 - IPC

FIELD: radiation shielding and masking systems, those producing illumination effects (advertisement, decorative lights), data display systems.

SUBSTANCE: proposed device that can be used for dissipating electromagnetic radiation, such as light, radio waves, X-rays, as well as for dissipating particle streams is, essentially, multilayer screen some of whose layers are deformable ones. Electric field is built up between two electricity conducting layers due to voltage applied to these layers. In the process conducting layers are split into segments and separate electrodes are brought to respective layers. Voltage applied to separate segments permanently varies with the result that electric field produced is nonuniform and deformable layers are embossed due to nonuniformity of attractive forces between electrodes, this embossed pattern permanently changing its configuration. Radiation (light of different ranges, radio and electromagnetic waves, particle streams) passed through screen or reflected therefrom dissipate due to optical nonuniformity. Kind of dissipation continuously varies due to changes in embossed pattern. Segments of conducting layers can be energized obeying different laws including pseudorandom one.

EFFECT: reduced specific surface power of incident radiation.
