CONTROLLABLE HETEROGENEOUSNESS Russian patent published in 2006 - IPC H03H11/40 H03J3/00 H01Q15/14 

FIELD: radio engineering, UHF engineering, possible use for realization of methods for transmitting and receiving information without native source of bearing signal.

SUBSTANCE: controllable heterogeneousness is made in form of flat-lamellar structure, including controllable layer in form of two-dimensional periodical array of stripes or rods, in gaps of which controllable elements are included, electrically connected to controlling signals generator. Heterogeneousness also contains two identical two-dimensional periodical passive arrays, separated from controllable layer by first air layer, and divided by second air layer. Each one of two arrays independently from each other is mechanically connected to controllable two-dimensional periodical array of stripes or rods by a pair of screw transmissions, positioned on opposite sides of arrays, and also serially connected station of radio-technical reconnaissance, computing device, transformer, two executive step reverse electric motors, control inputs of which are connected to two appropriate outputs of transformer, two inputs of which are connected to appropriate two outputs of computing device. Each pair of screw transmissions is connected to appropriate electric motor. Thicknesses of first d₁ and second d₂ air layers and conductivity B of identical arrays are computed by aforementioned computing device using data about bearing signal wave length of side emission source, determined by radio-technical reconnaissance station, in accordance to given mathematical formulae, produced from condition for manipulation of amplitude and phase of passing and reflected signals.

EFFECT: decreased mass-dimensional characteristics with increased volume of transferred information.
