Design of Low-Profile Frequency-Selective Rasorbers Based on Three-Legged Loaded Element

<div>Surface current distributions of the TLLE at different operating frequencies. (a) <i>f</i><sub>A1</sub>: lower absorption frequency, (b) <i>f</i><sub>T</sub>: parallel resonant frequency, and (c) <i>f</i><sub>A2</sub>: higher absorption frequency.</div>
