DESCRIPTION:Speakers: Pavel Nikitin (Scientific and Technological Center o
 f Unique Instrumentation of RAS)\nOne of the leading areas in telecommunic
 ation technology is the development of high-speed devices. At present\, th
 e use of the acousto-optical (AO) effect to control radiation is promising
 . Devices based on this effect are used in the ultraviolet\, visible and i
 nfrared ranges. One of the main problems of using the AO effect in the ter
 ahertz (THz) range is the low diffraction efficiency (four orders of magni
 tude less than in the visible range) due to an increase in the radiation w
 avelength. This work is devoted to modeling the operation of the AO filter
  of a THz radiation\, in which the collinear geometry of the interaction o
 f the radiation beam with the ultrasound beam is used. In contrast to the 
 well-known works in which the sound beam was assumed to be homogeneous and
  the chalk plane wave front\, we used the model structure of the sound bea
 m. The nonpolar liquid hexane (C6H14) was chosen as the AO interaction med
 ium\, since it is characterized by acceptable values ​​of transparency
  and attenuation of ultrasound.\nThe work was supported by RSF grant No.18
