Devices with such capability were considered science fiction until recently. It looks like the applications for this research is flying along much faster than expected. The debate should begin now on how to regulate it. The military applications are obvious, but privacy concerns are enormous. Amazing how life imitates art.

So you might want to say that this material can work with wavelengths of light in the 5 to 50 centimeter range. (<a href="http://en.wikipedia.org/wiki/Electromagnetic_spectrum" rel="nofollow">A rough non-calculated approximation of 18 to 1 gigahertz part of the electromagnetic spectrum</a>). This range includes the microwaves we use to cook our food, though that deals with the frequency side of the equation. In any case, welcome to the blog, Nina.

Corrected to "frequencies." Thanks. Corrected to “frequencies.”
