DOI: 10.1002/mop.32789
Abstract: Switchable rasorber operating between rasorbing and absorbing states can effectively improve its stealth performance within the passband. However, the existing switchable rasorbers utilize single‐order frequency selective surfaces (FSSs), limiting their transmission bandwidth. This work proposes… read more here.

DOI: 10.1109/tap.2019.2916739
Abstract: In this paper, we present a frequency-selective rasorber with tunable transmission window located within the absorption band. The rasorber maintains a low reflectivity, which is less than −10 dB in broadband during the tuning process.… read more here.
