This site contains various applets and animations of physical processes, demonstrating various ideas in waves, optics, mechanics, and thermodynamics. The site also contains information on the theory behind diffraction...

This article from SPIE discusses an electron-beam-lithography technique which fabricates diffractive optical structures such as classic Fresnel-zone-plate lenses with fine features. Diffractive optical elements are...

This resource illustrates the interference patterns for diffraction through double slits. A series of sources, electrons, protons, neutrons, photons, and pions, can be chosen for the virtual experiment. The energy of the...

This course, presented by MIT, explores electromagnetic phenomena in modern applications. Some of these include: wireless communications, circuits, computer interconnects and peripherals, optical fiber links and...

Watch this video from Duke University. The cloak, made with advanced 'metamaterials,' deflects microwave beams and may find a variety of wireless communications or radar applications.
