Abstract
Terahertz imaging proves advantageous for metamaterials characterization since the interaction of THz radiation with the metamaterials produces clear patterns of the material. Characteristic "finger prints" of the crystal structure help locating defects, dislocations, contamination, etc. TDS-THz spectroscopy is one of the tools to control metamaterials design and manufacturing. A computational technique is suggested that provides a reliable way of calculation of the metamaterials structure parameters, spotting defects. Based on missing data analysis, the applied signal processing facilitates a better quality image while compensating for partially absent information. Results are provided.
