Title: Device for screening and absorption of electromagnetic fields, especially in the radio-frequency band, using metal-fibre concrete
Inventor: BUSCH DIETER DIPL ING
IPC: H01Q15/14
Filed: 1981-08-06
Abstract: The present patent application describes a structural material which makes it possible in a simple manner to implement a screening effect, which is considerably improved in comparison with conventional building materials, against radio-frequency and microwave radiation. The physical principle of the screening is based on absorption and/or reflection of the incident electromagnetic radiation. This effect is brought about by special shaping and arrangement of metal parts which are a component of the concrete mass and at the same time contribute to increasing the strength. Depending on the selection of the parameters of the metal parts, which can also be constructed as electromagnetic tuned circuits with concentrated components and can possibly be additionally used for metal-grid reinforcement, the reflection and absorption properties can be varied within wide limits, as a function of the frequency.
