Corrosion, mold and moisture can be detected under outer layer of structures, such as surfaces associated with vessels and/or buildings, using nondestructive evaluation (NDE). Characterizing the dielectric properties of materials associated with a target can be executed by directing primary microwave energy from a source towards a target, receiving secondary microwave energy signals returned from the target, analyzing the secondary microwave energy signals, and characterizing dielectric properties of materials associated with the target based on analysis of the secondary signals. A system for non-destructively characterizing a target material's dielectric properties can includes a microwave energy source, a waveguide for directing microwave energy towards a target, a receiver for receiving microwave signals reflected off targets, an analyzer for assessing the difference between incident and reflected microwave signals to determine the presence of corrosion within a target or a targeted area, and an indicator for providing results of analysis.
