Microstructures Improve Data Transfer

Facebook X LinkedIn Email
SALT LAKE CITY, March 12, 2014 — Microscopic structures that use light in metals to relay information could improve the speed of wireless technology and enable the printing of magnetic materials. Electrical engineers at the University of Utah, using an inkjet printer, developed a new technique that controls electrical conductivity within such microstructures. This could rapidly produce superfast components in electronic devices, according to the researchers. Using an inexpensive printer and two color cartridges (one silver and one carbon), the team printed 10 different plasmonic structures with a periodic array...Read full article

    light
    Electromagnetic radiation detectable by the eye, ranging in wavelength from about 400 to 750 nm. In photonic applications light can be considered to cover the nonvisible portion of the spectrum which includes the ultraviolet and the infrared.
    terahertz
    Terahertz (THz) refers to a unit of frequency in the electromagnetic spectrum, denoting waves with frequencies between 0.1 and 10 terahertz. One terahertz is equivalent to one trillion hertz, or cycles per second. The terahertz frequency range falls between the microwave and infrared regions of the electromagnetic spectrum. Key points about terahertz include: Frequency range: The terahertz range spans from approximately 0.1 terahertz (100 gigahertz) to 10 terahertz. This corresponds to...
