technology. One example is the claim of being able to image through building walls.7 Another is the claim of being able to identify shipwrecks and their contents on the ocean floor.8 While millimeter-waves can “see through” some wall material such as drywall or dry plywood, they cannot see through structural materials (see Chapter 2, Figure 2-5).

In light of such misconceptions, the committee decided that this report should briefly and systematically address expectations, both real and fictional, and help bring into focus cases in which this technology has promise and instances in which it offers no potential benefit as an antiterrorism technology.
