dc.description.abstractWideband electromagnetic characterization of Portland cement concrete (PCC) has been investigated in this study. This is necessary to correlate the material properties of PCC with its physical condition and hence aid in nondestructive evaluation of practical PCC structures. A test fixture has been designed to characterize PCC test specimens in the frequency range of 100-1000 MHz. Measurements have been performed in both time domain and frequency domain. The focus of this research has been to investigate time domain techniques for the characterization of PCC specimens under different test conditions. A simplified TDR measurement technique using one-port calibration scheme has been proposed for the research. Measurements have been carried on reference materials (e.g. Teflon) to verify the accuracy of the proposed technique. Extensive calibration and de-embedding have been studied to minimize the systematic errors involved in the measurement process. A computer simulation based verification process has been studied to validate the proposed calibration and de-embedding scheme. Sensitivity analysis and study of repeatability of the measurement process has been done as well.en
