Measuring of the shielding effectiveness of electromagnetic field of brick wall in the frequency range from 1 GHz to 9 GHz

This paper deals with measuring of shielding effectiveness of electromagnetic field. The measurements were focused on measuring of shielding effectiveness in the range of high frequencies from 1 GHz to 9 GHz in the step 0,2 GHz. The measured object was a brick wall with a thickness 25 cm. Size of brick wall were 2×2 m. Measurement was preformed according IEEE Standard, Method for Measuring the Effectiveness of Electromagnetic Shielding Enclosures. Measurement was performed in the non-reflection chamber because exterior influence. Brick wall consisted of bricks porotherm 25×25 cm. The laying of bricks were the same as in the construction of buildings.
