摘要

Recently, we showed that single negative media can significantly enhance the sensitivity of near-field probes. Inspired by this recent finding, we propose a new near-field probe that uses only one single split ring resonator instead of a periodic arrangement of these resonators. We show through numerical simulations that the new proposed probe lead to significant enhancement in the sensitivity as measured by the change in phase in the reflection coefficient. Experimental tests were conducted to detect the presence of a small aluminum block located behind a layer of ground chicken (lossy medium). Preliminary results show that with our new probe, a phase change in the reflection coefficient of 14 degrees can be achieved for 2 mm thick ground chicken and 6.24 mm aluminum cube at an operation frequency of 1.16 GHz.
