#Measurement (contract analysis) service
KEYCOM has not only has a highly-advanced products in the 10μHz-300GHz frequency range, but also accumulates expertise in measurement techniques.
Our company is a member of the JIS committees for the following measurements:
・Permittivity measurement
・Electromagnetic absorption ratio measurement
The measurement method of the reflection ratio of electromagnetic absorbers, which KEYCOM developed, was accepted as a standard in The Institute of Electronics, Information and Communication Engineers. The detail was reported at the session of IEEE IMS2005. (Orlando, FL, USA March 29-30, KEYCOM; 30 march in 2005).
