Printable Filters Manage THz Communications
SALT LAKE CITY, Feb. 27, 2015 — 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...
