We apply inverse-design methods to produce two-dimensional plasma metamaterial (PMM) devices. Backpropagated finite-difference frequency-domain (FDFD) simulations are used to design waveguides and demultiplexers operating under both TE and TM modes. Demultiplexing and waveguiding are demonstrated for devices composed of plasma elements with reasonable plasma densities of approximately $7$ GHz, allowing for future in situ training and experimental realization of these designs. We also explore the possible applicability of PMMs to nonlinear boolean operations for use in optical computing. Functionally complete logical connectives (or and and) are achieved in the TM mode.

用于光学计算的等离子体超材料器件的逆向设计

我们应用逆向设计方法来生产二维等离子体超材料 (PMM) 设备。反向传播有限差分频域 (FDFD) 仿真用于设计在 TE 和 TM 模式下运行的波导和解复用器。对由等离子元件组成的装置的解复用和波导进行了演示，该等离子元件的合理等离子密度约为$7$ GHz，允许未来对这些设计进行现场培训和实验实现。我们还探索了 PMM 对非线性布尔运算的可能适用性，以用于光学计算。在 TM 模式中实现了功能完整的逻辑连接词（或和和）。
