One seismometer is often not enough to reliably detect earthquakes or human activity such as underground nuclear tests.

Abstract: A phased array loaded with a reactive impedance surface (RIS) is proposed for wideband wide-scanning performance. The mushroom-like RIS structure, etched on the same printed circuit board ...

On Jan. 26, 2026, the Submillimeter Array (SMA) on Maunakea crossed an important threshold for time-domain astronomy. For the ...

Preventing adversaries from interfering with communications is crucial to national security. Tactical satellite ...

The Pentagon is searching for new ways to protect military satellite communications from electronic attacks in space. MIT Lincoln Laboratory engineers are now developing a lightweight antenna system ...

Abstract: A dual-polarized phased array antenna is presented with wide-angle scanning capability in this article. To improve the mutual coupling in the array, a current cancellation method (CCM) is ...

The Vantage NXT system provides three encoder inputs that enable users to track position, movement, and rotation during data acquisition. Researchers can use encoder count data for Pulse-on-position ...

The ImunifyAV malware scanner for Linux servers, used by tens of millions of websites, is vulnerable to a remote code execution vulnerability that could be exploited to compromise the hosting ...

This paper presents a low-profile, tightly coupled dipole array (TCDA) antenna to achieve broad-angle scanning with excellent impedance matching over a wide bandwidth. The antenna element is ...
