A new beam pattern devised by University of Rochester researchers could bring unprecedented sharpness to ultrasound and radar images, burn precise holes in manufactured materials at a nano scale -- ...
Ion beam lithography is used to create fine nanostructures on a surface, such as circuit boards. It can be used to directly write on the material, rather than using a photomask, as in photolithography ...
Jan. 27 (UPI) --University of Rochester researchers have developed a novel beam pattern that promises to lend unprecedented sharpness to ultrasound and radar images. The beam's mathematical pattern ...
