Abstract: We investigate a fast algorithm to search for the location of a small anomaly by using microwave. The algorithm is based on the structure of nonzero singular vectors associated with nonzero singular values of a complex-symmetric matrix, whose elements are measured S-parameters. Experimental and simulated results show the effectiveness and limitations of the investigated algorithm for real-world microwave imaging.

Keywords: Fast algorithm, microwave, S-parameters, experimental results
