and Figures 2 and 3 yield: 



Transmission coefficient = T = 0.19 

 Reflection coefficient = R = 0.73

By comparing the predicted results for the model (eq. 78}, and 

 for the prototype (eq. 71), it is seen that the scale effect has 

 increased the reflection coefficient, whereas the transmission coeffic- 

 ient is decreased. For the present example the scale effects are not 

 pronounced, but in other situations it may be a very important factor 

 to consider (Figs. 6, 1 , and 8)
