DOI: 10.1049/el.2019.2429
Abstract: This Letter presents the design of a frequency-selective rasorber that selectively absorbs undesired (out-of-band) signals and selectively transmits desired (in-band) signals by using planar resistor technology without lumped elements. To implement the selective absorption characteristic… 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.
