RAPID Lithography: New Photoresists Achieve Nanoscale Resolution

Over the past decade, researchers have shattered the traditional view of the diffraction limit. Using new techniques, they have obtained resolution far smaller than the wavelength of light excitation or emission. Similar concepts are now being applied to photolithography, making it possible to create nanoscale features in a photoresist using visible or near-infrared light. more>>


Heinrich Hertz and the Foundations of Electromagnetism

Heinrich Rudolf Hertz did not grasp the practical importance of his work during his lifetime, but his research into electromagnetic radiation laid the foundation for all wireless communications. The education and experience of this 19th century German scientist prepared him to make his monumental discoveries on propagating electromagnetic waves. more>>
