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.
