T. Lasri et al., RESEARCH NOTE - A LOW-COST MICROWAVE SYSTEM FOR NON DESTRUCTIVE CONTROL OF TEXTILE WEBS, The Journal of microwave power and electromagnetic energy, 31(2), 1996, pp. 122-126
The progress in microwave technology allows one to think that original
and low cost sensors for various applications may be feasible. In thi
s paper a sensor devoted to the characterization of material webs is p
resented. This sensor is based on the use of a complex correlator asso
ciated with a measurement cell. The first attempt was made in microstr
ip technology at a frequency of 10 GHz.
