【Abstract】 The computation methods of electromagnetism parameters, electromagnetic wave frequency and medium slice thickness in microwave measuring for composite material were analyzed. According to the spreading characteristic of electromagnetic wave, the limitation and deficiency of microwave measuring in composite material were pointed out. Due to the effect of the air layer in the composite material, the swing attenuation and phase delay of transition wave and the solutions were discussed. The transmission coefficient was calculated with the effect of air layer in composite material. The developing tendency of microwave measuring in composite material was discussed.更多还原
