METHOD OF TRANSMITTING VOICE MESSAGE AND DEVICE THEREFOR Russian patent published in 2015 - IPC H04B10/00 

FIELD: radio engineering, communication.

SUBSTANCE: method includes generating carrier electromagnetic oscillations, modulating the oscillations with an electrical signal containing transmitted information, propagating the oscillations over a distance, receiving and converting the oscillations into the original electrical signal; the frequency of the electromagnetic oscillations is in the X-ray wavelength range, and the device consists of a transmitter and a receiver, the transmitter comprises an analogue-to-digital converter connected to a light modulator, and an X-ray tube, the vacuum envelope of which has input - optically transparent and output - radiotransparent windows, as well as photocathodes, one or more dynodes and an anode with a target. The modulator is optically connected through the input window with the photocathode, the anode is connected to a high voltage source and the output window is designed to transmit X-ray pulses to the input of the receiver, comprising series-connected X-ray detector, amplifier and digital-to-analogue converter of the electrical signal, the output of which is the output of the receiver.

EFFECT: high noise-immunity and stealthiness of transmitting a voice message.
