Voltage-controlled half adder via magnonic inverse design
Abstract
In this work, we report a magnonic device capable of dynamic control over magnon propagation. By leveraging voltage-controlled magnetic anisotropy on yttrium iron garnet waveguides, we have carried out simulations of an active demultiplexer and half-adder designed using inverse design principles. A high output intensity multiplexer was similarly developed via inverse design to mitigate the magnon re-emission issue in Y-shaped combiners. Trapezoid electrodes were also introduced to minimize magnon intensity losses due to the magnetic anisotropy gradients across the cascading magnon circuit. The magnonic half-adder, constructed using active demultiplexers and a multiplexer, showcases the potential of magnonic logic circuits for binary addition operations.
