Definitions

  • the invention relates to window glazing, consisting of double glazing with a sealed intermediate space, in which a translucent layer (3) with a defined surface resistance is arranged in the area of the outer pane and in which the inner pane is provided with a radar-reflecting, optically transparent layer (6).
  • Such window glazing has already been described in DE 40 08 660 A1. It is constructed according to the principle of the Jaumann absorber, i.e. the portion of the incident electromagnetic radiation reflected in the area of the outer pane becomes that portion of the radiation which is superimposed on the inner pane by the reflection layer arranged at a distance of about a quarter of the operating wavelength, due to the extinction of both parts takes place.
  • the glazing described has proven itself in use, but in the manufacture of such glazing there is the problem that the known layers vapor-deposited onto the outer pane cannot be produced with the required precision and reproducibility.
  • the single figure of the drawing shows a section through an insulating glazing for buildings with two separate panes 2 and 7. In between there is an evacuated or gas-filled intermediate space 5.
  • the outer pane 2 which can also be designed as an assembled double pane, are parallel wires 3 arranged.
  • the dimensions of the glazing for an operating frequency of approximately 1 GHz result in the following advantageous dimensions: the thickness of the outer pane 2 is 6 to 18 mm, that of the inner pane 7 is approximately 4 to 12 mm.
  • the width of the interspace 5 is selected in the range 16 to 35 mm.
  • the distance between two adjacent wires 3 is approximately 10 to 30 mm.
  • the wire diameter can be freely selected within a wide range. In the exemplary embodiment, wire diameters of less than 0.5 mm were chosen in order not to significantly restrict the optical transparency.
  • the dimensioning of the distance d between the parallel wires and their angle ⁇ to the direction of polarization of the incident electromagnetic radiation R significantly influence the intensity of the reflection suppression.
  • the window glazing according to the invention uses the functional principle of the known Jaumann absorber, the necessary amplitudes and phases of the respective proportions of the electromagnetic radiation are adjusted by means of the distance between the wire-shaped electrical conductors 3 with each other and by means of the distance between the wires 3 and the radar reflecting layer 6 on the inner pane 7.
  • the layer 6 on the inner pane 7 is designed as a heat protection layer.
  • metallic reflection can be assumed.
  • the purpose of the invention is now to set the reflection factor r 1 of the layer 3 of the outer pane to a certain value with easily realizable and reproducible means.
  • the surface resistance of the layer 3 consisting of the parallel wires is about 300 ⁇ / ⁇ , about 38% of the incident electromagnetic radiation being reflected.
  • the reflection factor r 1 generated by the parallel wires 3 is strongly dependent on the polarization direction of the incident electromagnetic radiation. For this reason, the wires are arranged approximately in the region around 45 ° to the direction of polarization. The position of the wires within the window glazing is easily adaptable to the requirements in the manufacturing process. The adjustment to the conditions at the installation site can also be carried out by setting the optimum angle of rotation to the predominant direction of polarization.
  • the parallel wires act in a similar way to a known vapor-deposited resistance layer and moreover have a defined and adjustable surface resistance.
  • the distance d between the wires affects the equivalent sheet resistance of the window glazing. If the distance is less than 1 cm at an operating wavelength of 1 GHz, the surface resistance is too small. With a large wire spacing (d> 3 cm), the arrangement no longer appears homogeneous, since the wires begin to act as discrete radiation elements, as a result of which the suppression of reflection deteriorates increasingly.
  • the wire diameter is advantageously chosen to be very small. For reasons of optical transparency, a was used in the exemplary embodiment Diameter selected less than 0.5 mm.
  • the arrangement of the wires according to the invention does not act in the specified dimensioning like an arrangement of flatly distributed discrete radiation elements, which because of their frequency selectivity act narrow-band, but the entirety of the wires acts as a homogeneous layer with a precisely defined surface conductivity and also has the advantage of high optical transparency .
