Compare of fabric and brick wall as shielding material dependence on electromagnetic field

The electromagnetic field is a much discussed topic, especially now with the advent of 5G networks. The general public is concerned about the possible impact of the electromagnetic field on human health. By using wireless technologies, we increase the influence of the electromagnetic field on the human body. The basic measures for the protection against electromagnetic radiation are: 1. shielding of the radiation source, 2. shielding of the workplace, 3. personal protective equipment, 4. reduction of radiation in the immediate vicinity of the radiation source. In the household it is possible to shade the “working” environment which is our house. In this paper, we focused on measuring the shielding efficiency of the electromagnetic field. Shielding effectiveness is an indicator of the shielding ability of the material. The measured objects were a brick and a shielding fabric, which can be used practically anywhere. The research focused on the frequency range from 1 GHz to 9 GHz. The results showed the shielding ability achieved by the brick material and the shielding fabric.
