Southeast University and Hawkeye have established a joint research center focusing on vehicle millimeter-wave radar technologies, said Professor Hong Wei, IEEE fellow, director of the State Key Laboratory of Millimeter Waves
of Southeast University.
Antenna circuit boards that transmit/receive millimeter waves
require low transmission losses.
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).

The sheet is measured via millimeter waves
based on the Frequency Modulated Continuous Wave Radar runtime method.
Operating in the 60 and 80 GHz bands, Siklu's radios now supplement Alcatel-Lucent's 9500 MPR family by introducing the support of millimeter waves
and providing a solution for short-range, high-capacity small cell backhaul in very dense environments.

are the highest band of radio waves and operate at a frequency range of 20-300 GHz.
The other type of scanner uses millimeter waves
, which have wavelengths that fall between infrared and microwave.
It uses a part of the electromagnetic spectrum called millimeter waves
. These waves lie just to the right of microwaves, which means they carry a little more energy than microwaves do.
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.
Termites inhabiting an air-dried wood block of western hemlock were detected by a nondestructive imaging technique using millimeter waves
at a frequency of 100 GHz with 10-mW output power.
