PDMS-based skin-equivalent phantom for propagation studies in the 58–63 GHz range

A solid phantom simulating the same reflection coefficient at the air / phantom interface as at the air / skin interface is developed for on-body propagation assessment in the 58–63 GHz range. The phantom consists in a grounded lossy dielectric sheet made of polydimethylsiloxane (PDMS) and carbon black powder. The paper describes the characteristics of the phantom and provides an example of its application in propagation studies at 60 GHz.
