Twist It, Bend It, But Antenna Still Works

Antenna technology takes a swift turn with a new alloy allowing bendable, unbreakable, miniaturized reception. Do you see this technology succeeding? Do you envision other uses for this alloy beyond antennas?

Standardizing Government Information Sharing

In "New Document Provides Framework for Interagency Data Sharing," Henry Kenyon describes a newly released document that sets common standards for data security and risk management: the NIST Special Publication 800-37, Revision 1, Guide for Applying the Risk Management Framework to Federal Information Systems: A Security Life Cycle Approach (NIST SP-800-37).

You don't have to be a dummy to need help preparing for a test.

SIGNAL Says: Dr. Simon Cotton

"There's potential here to take this forward. The operating systems at these frequencies are just mind blowing."--Dr. Simon Cotton, the Centre for Secure Information Technologies, Queen's University Belfast

Cool App-titude: H&R Block Tax Answers

You know it's coming--tax season. There's a reason I went into publishing: I'm terrible at math. So for people with poor accounting skills like me, tools like the H&R Block Tax Answers app are a lifesaver.

I'm a fan of all things Discovery: Animal Planet, TLC, and of course the Science and Military channels. So I'm particularly excited about the Discovery News iPhone application.

Shape-Shifting Antennas Flex Their Muscles

Digital natives probably don’t remember how home TV viewers had to manually adjust “rabbit ears”—those odd-shaped dipole antennas that sat atop a TV sprouting wires and sporting any number of dials to turn in the hope of improving the picture. But when a recently uncovered use for an alloy comprising gallium and indium becomes widespread as the go-to material for antennas, the newest antennas may be able to adjust themselves without a human hand. Although only in the second stage of research, the combination of these well-known materials already has demonstrated that when bent and twisted, antennas return to their original shape; when cut with a razor, they heal.

Antenna Advances Counter Bombs and Improve Communications

Researchers are pursuing advances in radio antenna technology to build communication equipment into body armor and to offer more capable and efficient methods for countering roadside bombs. Virtual modeling techniques incorporating developments in materials science currently are testing and verifying prototype equipment before physical testing begins. This combination of cutting-edge research and simulation has rapidly matured these antenna technologies and prepared them for initial operational evaluations.

Simulation Project Demonstrates Covert Applications

Researchers in the United Kingdom have completed a preliminary investigation into the use of millimeter-wave, body-worn antenna arrays to create mobile ad hoc networking for dismounted combat soldiers. The effort proved the feasibility and benefits of such a network as well as provided a platform for future study of the concept. Personnel involved in the experiments focused their work on the 60-GHz band, which offers the high amount of bandwidth necessary for troops to exchange large quantities of information on the battlefield. The short range of the communications enhances covertness by reducing the chance for enemies to exploit transmissions, and it also reduces interference.
