Approximations of the planar area
measure A (d = 2) and the volume measure V (d = 3) are straightforward:
On the other hand, the exponential factor creates large amplitude and phase deviations across that same planar area
. The planar array lies in the x-y plane; the plane wave region is also in the x-y plane but [z.sub.0] away from the array.
These remaining 0201 components require physical placement because they cannot be realized due to physical planar area
The increased biological relevance of information obtained from assays conducted with planar areas
greatly outweighs the additional effort and cost required to use them, and we strongly advise their use for the study of subterranean termites.
