Abstract

A flexible, low-profile, and polarization-insensitive absorber with a tunable absorption band is presented in this paper. The proposed metasurface absorber consists of a resonant liquid metal frequency selective surface (FSS) layer embedded in a thin (0.044λ) slab of polydimethylsiloxane (PDMS). By pneumatically controlling the position of liquid metal dipoles inside PDMS channels, continuous tuning of the absorption frequency is achieved over a 1.6 GHz (16 %) bandwidth in the X-band.
