Claim:
1. A system for detecting moisture characteristics of a material of a complex structure while the material is in situ, comprising: at least one moisture detection sensor embedded in the material of the complex structure while the material is in situ; and a controller in data receiving communication with the at least one moisture detection sensor; wherein the at least one moisture detection sensor comprises a transmitting portion embedded in the material on an exterior surface of the material and a receiving portion embedded in the material on an interior surface of the material, the material having a thickness defined between the interior and exterior surfaces, the transmitting portion being spaced apart from the receiving portion across the thickness of the material with the material being interposed between the transmitting portion and the receiving portion, wherein the transmitting portion transmits an electromagnetic microwave pulse through the thickness of the material interposed between the transmitting portion and the receiving portion, and the receiving portion receives the electromagnetic microwave pulse from the transmitting portion after being transmitted through the material interposed between the transmitting portion and the receiving portion; and wherein the electromagnetic microwave pulse is tuned responsive to an electromagnetic-energy absorption property of moisture.
