AB - <p style="text-align: justify;">In this paper, we first develop the mathematical modeling equations for
wave propagation in several transformation optics devices, including electromagnetic
concentrator, rotator and splitter. Then we propose the corresponding finite element
time-domain methods for simulating wave propagation in these transformation optics
devices. We implement the proposed algorithms and our numerical results demonstrate
the effectiveness of our modeling equations. To our best knowledge, this is the
first work on time-domain finite element simulation carried out for the electromagnetic
concentrator, rotator and splitter.</p>
