Resumo
© ACESThis article describes the measurement of the complex dielectric constant of pure concrete and a brick wall, in the frequency range up to 2 MHz, with a view towards more accurate material description in electromagnetic simulations. The measurement system is based on the use of the materials under test as the dielectric material placed inside a parallel plate capacitor, in series with an external known fixed resistor. The theory behind the measurement is covered, and the results of both real and imaginary relative dielectric constants for both materials are presented. Finally, an electromagnetic simulation showing the shielding effectiveness of a hollow box made of a brick wall is presented, using the measured data in comparison with data from a commercial simulator database.
