Considering the insufficient measurements for reflection and transmission characteristics of millimeter-wave channel and inaccurate calculation methods for propagation coefficients of multilayer building materials,an extensive investigation on the reflection and transmission characteristics of millimeter-wave channel at 40-50 GHz is conducted for 6G Integrated Sensing And Communications(ISAC).Firstly,a method for calculating propagation coefficients of multilayer building materials is proposed based on Fresnel theory and shooting and bouncing ray principle.Furthermore,extensive measurement campaigns at 40-50 GHz are carried out to obtain reflection and transmission coefficients of multilayer wood and glass using VNA-based millimeter-wave channel sounder.The results show that the measured values are in good agreement with the theoretical values and the propagation coefficient error is less than 0.1,which verify the accuracy and effectiveness of the proposed method.Besides,it is also found that the resonant period and effective brewster angle of reflection coefficient are dependent on polarization,incident angle,and material thickness.
