Abstract
This paper presents a nondestructive corrosion damage
detection method for reinforced concrete structures based on
the analysis of the electromagnetic signature of the steel rebar corrosion.
The signature of the corrosion on the scattered field upon
microwave illumination is first numerically analyzed. First-order
quality factor parameters, the energy and the mean propagation
delay, are proposed to quantify the corrosion amount in
the structure. To validate the model, low-profile ultra-wide-band
antennas (3–12 GHz) are fabricated and measured. Measurements
on 12 reinforced concrete samples with induced corrosion are
performed, using three different antenna setups. The experiments
demonstrate a good correlation between an increase in the corrosion
amount with a decrease in the energy and an increase in the
time delay of the propagated signal.
