摘要：

In this paper, we present experimental results of a thin impedance-matching metasurface (MTS) designed to operate in contact with the skin. This MTS was tested in the Ka-band using two different types of antennas and transmission was measured through several tissue-mimicking samples. The measurements show that the MTS enhances the signal penetration and minimizes reflection from the samples. Thus, the proposed MTS can be a powerful hardware advance for non-invasive biomedical applications, such as glucose sensing, while maintaining a subwavelength thickness.
