Abstract

In this paper, a reconfigurable textile electromagnetic absorber is proposed for wearable applications. The textile absorber is composed of a modified version of the well-known, artificial magnetic inclusion, the Split-Ring Resonator (SRR). The designed electromagnetic absorber provides extra freedom in ease of placement of either rectified load or a biasing circuitry for reconfigurability of the absorber or even both. Numerical studies are carried out in order to investigate the absorption strength from the proposed metamaterial absorber. Furthermore, the reconfigurability was achieved using a biasing varactor circuitry. Based on the numerical full-wave simulations, the proposed absorber structure exhibits an absorption of 99% at a frequency of 4.9 GHz under normal incidence when absorber is in ON state, while the peak absorptivity was shifted to higher frequency of 5.06 GHz when absorber is in OFF state with slight reduction in absorption level.
