As illustrated in Figure 11, positive light is being returned towards the source, whereas negative light is being returned away from the source, the boundary between them being drawn by the zero incident angle
For the current stage of investigation, a uniform wind velocity profile with little turbulence is required for studying the sole effect of opening sizes and wind incident angle
One can formulate the expressions based only on the incident angle
from air, [theta].
It is mentioned that vertically polarized wave experiences zero reflection at one incident angle
whereas, reflection is non-zero for horizontal polarization for all angles.
For TM polarization, as shown in Figure 3, bandwidths of the passband become wider as the incident angles

To change the incident angle
, it is sufficient to rotate the sample about the vertical axis that pass through the center o, while using the second degree of freedom of the sample for adjustments.
For R = 25% (in dotted-dashed line), the decreases in ACR can be found in the range of incident angles
from 90[degrees] to 135[degrees], while a slight increase occurs from 22.
At higher incident angles
and for pipes with higher aspect ratios, the distributions become more uniform as is evident in Fig.
For reflection measurements, to provide a needed incident angle
, a beam may pass through one of five holes in the equator of the sphere.
The hexagonal arrays of nonclose-packed bumps are similar to the structure of a moth's eyes and are designed to create a gradual change in refractive index, thus minimizing reflection over a broad range of wavelengths and incident angles
It will work out incident angles
for all the balls struck, leaving you with nothing to do other than judging the speed of the shot and keeping your hand steady.
