Modelling and calculating the shielding effectiveness of building materials

Abstract

This paper deals with modelling the penetration and absorption of high frequency electromagnetic field through the building material. It is focused on distribution of electromagnetic field in frequency range from 1.5 to 5.0 GHz, penetrating through the building material of different thickness. Nowadays in some domestic appliances and wide area exists a lot of electric and electronic devices, which are the sources of electromagnetic interference. To protect against electromagnetic interference in first case is important design concept of the devices, and some additional protection can be represented by construction works of rooms or building. For this reason, the article sets out to evaluate the shielding effectiveness and absorption of specific building materials in term of their harmful effect on the human body. Simulation of the penetration of HF electromagnetic field is created in the ANSYS HFSS.
