Scientists Use Diamond In First Continuous Room-Temperature Solid-State Maser
Scientists Use Diamond In First Continuous Room-Temperature Solid-State Maser

The maser (microwave amplification by stimulated emission of radiation), the older microwave frequency sibling of the laser, was invented in 1954. However unlike lasers, which have become widespread, masers are much less widely used because in order to function they must be cooled to temperatures close to absolute zero (-273°C).

    Scientists Develop Tiny Tooth-Mounted Sensors That Can Track What You Eat

    Monitoring in real time what happens in and around our bodies can be invaluable in the context of health care or clinical studies, but not so easy to do. That could soon change thanks to new, miniaturized sensors developed by researchers at the Tufts University School of Engineering that, when mounted directly on a tooth and communicating wirelessly with a mobile device, can transmit information on glucose, salt and alcohol intake.

    HAARP Facility To Resume Ionospheric Research

    Alaska’s super-power High-Frequency Active Auroral Research Program (HAARP) transmitters in Gakona, Alaska, will fire up again for the spring research campaign April 6 – 14. University of Alaska Fairbanks (UAF) Space Physics Group researcher and HAARP Chief Scientist Chris Fallen, KL3WX, told ARRL that more than 40 hours of “externally funded” experiments are in the queue.

    10 Cues You Need A 5G MIMO Channel Modeler

    How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G millimeter-wave and MIMO systems. This paper presents 10 cues that your organization may need a channel-modeling tool to supplement your 5G network planning efforts.

Antenna Factor Concepts

An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. The AF varies with frequency at the same presented field strength, but at a different frequency, the produced voltage at the connector is not constant. This white paper explains the process of creating AF data and how to use it.

Shielding Effectiveness Test Guide

Many products incorporate electronics and wireless communications and need RF interference testing. This requires shielding enclosures that need proper testing to ensure their correct operation.
