I've wondered the same thing, as I just applied to the Duke ECE program because of the metamaterials research being done there (and I'm finishing up my B.S. in physics right now). I didn't know how good my chances are, but they're flying me out to the open house, so things are looking pretty good.
So according to my personal anecdotal evidence, it shouldn't be too much of a stretch. Most of the programs I'm applying for are materials science, though, and I didn't apply to Stanford, Princeton, or any of the highest ranked EE schools, so I won't be able to offer any help there.
You could always try emailing one of the professors at one of those schools, though. I've been pleasantly surprised at how successful emailing random strangers can be.
