Abstract
A tunable impedance surface includes a varactor. The varactor comprises a bottom electrode formed on a surface of a substrate. First and second ferroelectric elements are on top of the bottom electrode and electrically connected to one another through the bottom electrode. A first top electrode is on top of and electrically connected to the first ferroelectric element and a second top electrode is on top of and electrically connected to the second ferroelectric element.
