range roughly from 7.5 mm to 3 mm long with frequencies of 40 gigahertz up to 100 gigahertz (40 billion to 100 billion cycles per second).
technology for optimization of tube quality, as well as time and cost savings
The Broadband Millimeter Wave
The five-pole millimeter wave
bandpass filters have been implemented using parallel-coupled, half wavelength resonator microstrip lines (positioned so that adjacent resonators are parallel to each other along half of their length).
The NLECTC evaluation found that the millimeter wave
device detected a wide variety of nonmetallic contraband, and officers felt that it acted as a deterrent, preventing many more illegal items from entering the facility than standard detection technologies.
is a whole body imaging system which can detect weapons, explosives and other security threats hidden under clothing without the need for the traditional pat-down.
Topics include millimeter-wave monolithic integrated circuits for WLAN, package technologies for millimeter-wave circuits and systems, antennas and channel modeling in WPANs, WLANs and WMANs, media access control protocols for millimeter-wave WLAN and WPAN, millimeter waves
for wireless networks, the WiMedia standard for WPANs, the millimeter-wave-based IEEE 802.16 standard for WMAN, the millimeter-wave dedicated short-range communications standard (including applications and experimental studies, interference in millimeter-wave WMAN cellular configurations, principles and applications of millimeter-wave radar, and optical generation and transmission of millimeter-wave signals.
The millimeter wave
radiated from the horn antenna was focused onto the optical object with a Teflon convex lens (50-mm diameter, 50-mm focal length) placed between the antenna and the object.
This weapons detection system uses a millimeter wave
camera combined with a video camera and special algorithm software.
The Brijot Imaging Systems Weapons Detection System, BIS-WDS Prime, uses passive millimeter wave
sensor technology to detect guns, knives, and bombs made of metal, plastic, and composite materials.
The system uses passive millimeter wave
sensor technology developed by Lockheed Martin.
London, UK 2/18/05 -- Smiths Group's Detection business has acquired Farran Technology, a developer of millimeter wave
technology for explosives detection, for 19 million [pounds sterling] ($36.0 billion) and as much as an additional 5 million [pounds sterling] based on performance targets.
