Abstract

Tento príspevok pojednáva o meraní zmeny účinnosti tienenia elektromagnetického poľa v závislosti na frekvencii. Meraným objektom bola drevená doska Medium Density Fiberboard (MDF12) s hrúbkou 12 mm. Meranie prebiehalo vo frekvenčnom rozsahu 1 GHz až 10 GHz. Meranie pozostávalo z merania účinnosti tienenia elektromagnetického poľa suchej MDF dosky a následne bola meraná účinnosť tienenia elektromagnetického poľa pri postupnom vysúšaní MDF dosky, ktorá bola nastriekaná vodou. (Meranie účinnosti tienenia MDF dosky v závislosti na vlhkosti v oblasti od 1 GHz do 10 GHz) This paper deal with measuring of change of shielding effectiveness of electromagnetic field in dependence on the frequency. Measured object was a wooden board Medium Density Fiberboard (MDF12) with a thickness of 12 mm. The measurement were focused on frequency range from 1 GHz to 10 GHz. The measurement consisted of measuring the effectiveness of shielding electromagnetic field dry MDF board and then was measured shielding effectiveness of electromagnetic fields in the gradual drying of the MDF board, which was sprayed with water. (Measuring of shielding effectiveness of MDF board depending on the moisture in the range from 1 GHz to 10 GHz)
