摘要：

To examine the microwave electromagnetic field (EMF) characteristics inside carbon fiber reinforced plastic (CFRP) structures, the quality factors (Q-factors) of reverberation chambers constructed of either CFRP or aluminum are evaluated and compared. In the CFRP structure, the four sidewalls and ceiling, which are originally made of aluminum, are replaced by CFRP panels, and then the uniformity of the field is evaluated. The standard deviation of the measured maximum electric field strength inside the chamber is less than 1.5 dB between 500 MHz and 6 GHz. The unloaded Q-factor of the CFRP chamber is almost identical to that of the all-aluminum structure below 2.5 GHz; however, it decreased by about 50 % between 2.5 GHz and 6 GHz compared to that of the all-aluminum structure. No significant difference is found in the loaded Q-factors of both structures.
