Measuring and simulation of the shielding effectiveness of electromagnetic field of brick wall in the frequency range from 0.9 GHz to 5 GHz

This paper deals with comparison of measuring and simulation of electromagnetic field shielding effectiveness. The experiment and simulations were focused on measuring and simulation of shielding effectiveness in the range of high frequencies from 0.9 GHz to 5 GHz. The measured object was a brick wall with a thickness 50 cm. Size of brick wall were 2×2 m. Measurement was preformed according IEEE 299-2006 Standard, Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures. The results from measurements were compared with simulation in Ansys HFSS program. Experiment was performed in the non-reflection chamber because exterior influence. Brick wall consisted of bricks porotherm 25×50 cm.
