 point is obtained substituting v = 2 into Equation 27, as follows:

Those calculated values were used to interpret the value for each non- 

 overlapping pixel of size O.lr/A by O.lr/A in the area within the lOr/A 

 radius from the origin. A diagram was then constructed by patching those 

 pixels over the entire area. The wave response diagrams for each incident 

 wave angle are shown in Figures 4 through 15. Notably, the values in the dia- 

 grams constitute the amplification factor which is defined as the ratio of the 

 total wave height to the incident wave height. Therefore, in subregions II
