Abstract :
In order to explore the application of a kind of electromagnetic absorbing concrete in the protective engineering, the electromagnetic attenuation properties of an L-shaped channel have been analyzed. By utilizing the vector network analyzer for tests, the HFSS and XFDTD for numerical simulations, the measurement data and computed results show that the L-shaped channel with axial length 2.5 m, wall thickness 5 cm, may realize 10 dB~40 dB attenuations of the electromagnetic amplitude within frequency range 400 MHz~6 GHz. These results can provide certain reference for the application of this material in building protective engineering´s main body and the passageway channels.
