Abstract

The system converts the energy of high frequency (HF) radiation in frequency range of 100kHz-100GHz by using HF absorbing powder/granules/foam provided on the inner surface or outer surface of solid geometry partially or fully, into other forms of energy, such that the resonance is minimized in the interior and exterior of solid geometry. The inner support materials and other substances in different states of aggregation are used for HF energy conversion.

Description

Bei elektrischen und elektronischen Geräten besteht die Aufgabe, Störstrahlung/Radarstrahlung/HF Felder nach außen zu vermindern bzw. ganz zu vermeiden sowie den Schutz vor eingestrahlter HF-Energie zu gewährleisten. Dies wird bekanntermaßen durch Unterbringung HF erzeugender oder vor HF zu schützender Baugruppen in verschiedenen Metallkammern realisiert. Der dazu erforderliche Aufwand ist jedoch relativ hoch und wirtschaftlich nicht immer gerechtfertigt.In the case of electrical and electronic devices, it is the task of reducing or completely avoiding interfering radiation / radar radiation / HF fields to the outside and of ensuring the protection against radiated RF energy. As is known, this is achieved by accommodating RF-producing or HF-protecting assemblies in various metal chambers. However, the required effort is relatively high and economically not always justified.

Der im Patentanspruch 1 angegebenen Erfindung liegen folgende Probleme zugrunde:

  • • Schutz vor Außenstrahlung zur Erhöhung innerer elektromagnetischer Sicherheitsabstände
  • • Schutz vor Innenraum-Reflektionen von innerer HF-Energie
  • • Schutz vor HF-Strahlungsresonanzen
  • • Schutz vor inneren Feldverzerrungen
  • • Schirmdämfungshilfsmittel zur Erhöhung der HF-Dichtheit
The indicated in claim 1 invention are based on the following problems:
  • • Protection against external radiation to increase internal electromagnetic safety distances
  • • Protection against interior reflections of internal RF energy
  • • Protection against RF radiation resonance
  • • Protection against internal field distortions
  • • Screening aid to increase RF leakage

Diese Probleme werden durch das in Patentanspruch 1 aufgeführte Verfahren gelöst. Zu sehen ist die Lösung des Problems in der Bilddarstellung Bild 1. Die mit der Erfindung erzielten Vorteile beim Vorhandensein von HF-Quellen im Inneren von Geometrien sind:

  • • es werden im Inneren von Metallvolumenanordnungen oder ebenen Anordnungen Feldreflexionen und Feldresonanzen vermieden
  • • nach außen erhöht sich der Schirmdämfungswert
  • • Effekte wie nicht gewollte Feldverzerrung, Feldstreuung und Ausbreitung stehender Wellen werden vermieden
  • • die Störstrahlungsentfaltung nach außen wird vermindert bzw. ganz verhindert
These problems are solved by the method set forth in claim 1. The solution of the problem in the image representation is shown. The advantages achieved with the invention in the presence of HF sources inside geometries are:
  • • Field reflections and field resonances are avoided inside metal volume arrangements or planar arrangements
  • • outward, the screen attenuation value increases
  • • Effects such as unwanted field distortion, field dispersion and propagation of standing waves are avoided
  • • The external radiation is reduced or completely prevented
