Plasmonic filters created with an off-the-shelf inkjet printer could enable blazing-fast wireless downloads and clearer cellphone calls using the terahertz spectrum. University of Utah researchers developed the filters, which are created with silver-metal ink similar to what is used for the production of circuit boards and tiny antennas. By filtering out unwanted frequencies, users can download information from the Internet or talk on a cellphone, for example, with less noise or interfering signals. University of Utah graduate student Andrew Paulsen, left, and professor Dr....Read full article

    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...
