A tabulation of transmission loss for common materials is included in the Appendix to this section (from Table 8.1, ref Bies and Hansen). A perfectly reflecting material has a transmission coefficient of 0 (STL = ∞), while the transmission coefficient of an opening is 1.0 IIncident IReflected ITransmitted Figure 2.
