通过测量强度相关函数随频率的变化和透射率的尺度依赖性，确定了微波辐射在金属球和电介质球的随机混合物中的扩散和吸收系数。我们发现一个狭窄的窗口的本地化频率和金属浓度。由于吸收的存在，这种转变是圆的。
The diffusion and absorption coefficients of microwave radiation in random mixtures of metallic and dielectric spheres are determined from measurements of the intensity correlation function with frequency shift and of the scale dependence of transmission. We find a narrow window of localization in frequency and metallic concentration. The transition is rounded by the presence of absorption.
