Abstract
The attenuation characteristics of electromagnetic wave penetrating brick wall with multilayer periodic structure are analyzed by the modal transmission-line method.The relation curves among the transmission and reflection coefficients,the incidence angle and frequency in electromagnetic wave penetrating the brick wall are obtained by calculation.The numerical calculation result is consistent with the simulation result.The attenuation of electromagnetic wave penetrating brick wall versus frequency (2-8 GHz) is measured by the electromagnetic wave measuring system.In comprehensive consideration of both the numerical calculation result and experimental measurement result,the attenuation of electromagnetic wave penetrating brick wall is about 15-25 dB when the frequency is between 2 and 8 GHz.关键词
