tecting the radiation become available. The expected applications include carrying out biological spectroscopy and imaging buried structures in semiconductors.

Rice University physicist Daniel Mittleman and his colleagues at Sandia and Los Alamos National Labs use a metamaterial to turn a stream of THz waves off and on. It's called a metamaterial since it consists of an array of microscopic split metal rings. The rings can be controlled by nearby electrodes; modulating the ring's capacitance, in turn, modulates the radiation; that is, the THz light (sometimes called T rays) can be switched so as to pass through or not. The modulator consists of 16 pixels in a 4 x 4 array. Mittleman reports that this is the first time the wavefront of a THz beam has been under electrical control, which is important because THz wavelengths may be good for imaging and this would be the first step in allowing that by sending light across a whole plane, not just as a linear burst. The switching speed, about 1 MHz, isn't fast compared to today's quickest data transmissions. But, Mittleman say, high bandwidth is not necessary for many of the imaging tasks that will be carried out by T rays. A larger 32 x 32 pixel array is now being designed.

WORLD'S HIGHEST-RESOLUTION PROJECTOR

If one were to stack 16 of the world's best high-definition projectors side-by-side (and on top of each other), the combined image projected would contain 33 megapixels. This is the resolution achieved by the world's highest-resolution projector, soon to be unveiled by the company Evans & Sutherland (E&S) of Salt Lake City, Utah.

Most projectors contain two-dimensional arrays of pixels, tic-tac-toe arrangements of tiny microelectromechanical systems (MEMS) devices that each light up with a particular color. Because fabricating 33 million of these devices is a tricky endeavor, the E&S projector only uses a single
