Quazi-optical varied light divider / 2255364
Device has circular metallic plate, in which a periodic matrix of rectangular slits is cut. Plate is positioned in such a way, that a falling beam of millimeter-long waves falls at an angle of 45° relatively to plate surface. Polarization of falling beam is parallel to plate surface. When direction of plate is such, that electric field is perpendicular to slits (i.e. electric field is directed transversely to lesser dimension of slits), plate transfers almost 100% of falling power. If the plate rotates around its axis for 90° (while keeping angle between falling beam and plate equal to 45°) in such a way, that falling electric field is parallel to slits, then plate transfers 0% and reflects almost 100% of falling power at an angle of 90° relatively to falling beam. By changing rotation angle between 0° and 90° both reflected and passed power can be continuously varied between values 0% and 100% from falling power. Light divider has cooling device for taking heat, absorbed from magnetic waves, away from edge of metallic plate.

The invention relates to the field of antenna technology and is designed to transmit and receive radio signals.

Known antenna with a radiating element in the form of a metallic vibrator consisting of a metal rod having a pattern of a toroidal shape with a minimum in the axial direction. Known antenna surface waves from the radiating element in the form of a dielectric rod having a pattern of needle shape with a maximum in the axial direction. (Reference elements of electronic devices. Edited Vindoline, Msica. M: Energy, 1978, str, 558). The disadvantage of these antennas is the inability to change the type of their spatial characteristics.

The prototype of the present invention is a laser antenna (U.S. patent No. 3404403, 343-700, 1968), in which the radiating element is ionized column of air created by a laser beam and is similar to the radiating metal rod. Design of laser antenna contains a laser that is designed to generate a laser beam, a focusing device, a circuit for connecting the source signals with the base of ionized air column.

The disadvantage of the laser antenna is the impossibility of changing the spatial characteristics of the emitter.

The objective of the invention is POPs is the W universal plasma receiving and transmitting antennas on the basis of plasma formation, which is the radiating element of the antenna and generated by the plasma generator, which provides a change in its characteristics due to changes in the properties of plasma formation, in which the antenna operates in the mode of metal or dielectric rod. The control parameters of the plasma generator, such as a change in current in the supply pulse, leads to changes in the concentration of charged particles in a plasma formation and causes the change of its properties that match a given mode of operation of the antenna.

Changing functions of plasma formation, change the antenna type. Thus there is the possibility of controlling the shape of the antenna directional diagram: toroidal with a minimum in the axial direction in the case of performing the function of a metal rod, a needle with a maximum in the axial direction in the case of a function of the dielectric rod, and the position of the plane of polarization of electromagnetic waves: in the case of a metal rod is parallel to the axis of the antenna, in the case of a dielectric rod is perpendicular to the axis of the antenna. The control parameters of the plasma generator, such as a change in voltage across its electrodes, allows you to create a plasma formation of different lengths, which expands the range of operating wavelengths and the Tenna. This is a technical result.

The technical result is achieved due to the fact that plasma antenna with a radiating element in the form of plasma formations containing a power source and a source of information signals, characterized in that the anode of the plasma generator is designed as a segment of the waveguide, and it is equipped with a control device operating modes of the antenna, consisting of devices interchange of information signals and signal power, one of which is connected to the cathode, and the other control electrode of the plasma generator, and a switch connected to the information line with the device junction that is connected to a source of information signals, and the power source through the device junction connected to the electrodes of the plasma generator.

The plasma device transceiver antenna shown in the drawing.

The plasma generator consists of a casing 1, a rod cathode 3, a hollow cylindrical anode 2 and the rod control electrode 4 located between them is perpendicular to the axis of the generator. The control device operating modes of the antenna as a metal or dielectric rod contains the device junction 5 and 6 and the switch 8.

Unlike laser antenna radiating element plasma antenna t is aetsa plasma formation, generated by the plasma generator, the control parameters which the control unit changes the properties of the plasma formation and the antenna as a whole. When this plasma antenna operates in pulsed mode - its radiating element is created only at the time of reception and transmission of information.

The power source 7 to the command switch 8 generates high-voltage pulses for the power of the plasma generator and firing pulses to initiate the process of formation of plasma formation and can be performed, for example, in the form of storages of electric energy (Ball lightning in the laboratory. Sat. articles edited Refarming and other M.: Chemistry, 1994, p.16). Device junction 5 and 6 are similar and are used for decoupling of high-voltage signal power and frequency of the information signal can be performed, for example, in the form of related segments of transmission lines without galvanic connection (Reference elements of electronic devices. Edited Vindoline, Msica. M: Energy, 1978, str-467). Switch 8 serves to control the operating modes of the antenna and switching signals and can be performed, for example, in the form of a set of electronic key devices (ibid, p.166, 474-475; Handbook of electronic devices, edited by Dupline. M: Energy, 1978, str).

Source p is Tania 7 plasma generator and the source or the receiver high-frequency information signal 10 is connected to the plasma generator through the device junction 5 and 6, whose positive outputs connected to the anode 2 of the generator and the negative output of one 5 is connected to the cathode 3 and the other 6 to the control electrode 4. The information signal on the information line from the source 10 is supplied to the generator through the switch 8 and the device junction in their negative outputs.

To create an emitter in the form of plasma formation 9 to the electrodes 2 and 3 of the plasma generator according to the command of the switch 8 from the power source 7 through the device junction 5 and 6 serves high-voltage pulse power supply with parameters corresponding to the operation mode. Also served a triggering pulse to the control electrode 4. At the same time, when the antenna mode metal vibrator switch 8 sends information signals through the device junction 5 to the cathode 3, and the excitation of the radiating plasma formation, which in this case is analogous to a metal rod, similar to the excitation single-ended Dildo. And when working in the mode of the dielectric rod antenna switch 8 sends information signals through the device junction 6 to the control electrode 4, the electrode 4 performs the function of exciting the vibrator in the round waveguide formed by the walls of the anode 2 and the plasma formation is a function dielectrics the second rod, inserted in the waveguide.
