Possibility of electromagnetic shielding using salt transparency liquid

This paper presents the properties of electromagnetic interference (EMI) shielding with transparency liquid in many cases of quantity of salt from 0% to 20% concentrate solution. The comparison is done under semi-anechoic chamber at 3 meter distance with Bilog antenna from 30 MHz to 1,000 MHz frequency range. It is found that in higher salt concentrate solution results a trend of high EMI shielding performance up to 23 dB.
