为了实现高性能紧凑型毫米波集成电路，本文提出了基于镶嵌优化思想的NRD波导器件优化设计方法。为了有效地优化NRD导向装置设计区域内的像素图案，提出了基于二进制表示的遗传算法、差分进化算法、和声搜索算法、萤火虫算法和粒子群优化算法。为了证明这些基于种群的优化的有用性，首先进行基于问题解决成功率的比较研究。为了进行这项研究，四个NRD电路组件的设计，其中包括低串扰波导交叉，T分支功率分配器，弯曲波导，和频率解复用器。所提出的最佳器件实现了高于99.9%，49.9%的高传输效率：在60 GHz时为49.9%，99.9%，在59 GHz和61 GHz时为96.4%，98.5%。此外，除了频率解复用器之外，相同的NRD波导组件也被设计为宽带操作，并且实现了大约5GHz、4GHz和3GHz的宽带宽。为了提高计算效率，数值模拟采用了二维全矢量有限元方法。本文演示了详细的实施过程中开发的进化方法的材料分布在NRD引导设备的设计区域，开发的优化方法的比较研究，并提出了高属性的NRD电路元件的实现基于NRD的高性能紧凑型毫米波电路。
In this paper, efficient optimal design approaches based on mosaic optimization concept are developed for NRD guide devices to realize the high-performance compact millimeter-wave integrated circuit. Binary representation-based genetic algorithm, differential evolution algorithm, harmony search algorithm, firefly algorithm, and particle swarm optimization are developed to efficiently optimize the pixel pattern in the design region of NRD guide devices. To demonstrate the usefulness of these population-based optimizations, a comparative study based on the problem-solving success rate is conducted first. To carry out this study, four NRD circuit components are designed which include low crosstalk waveguide crossing, T-branch power splitter, bending waveguide, and frequency demultiplexer. The proposed optimal devices achieve high transmission efficiencies greater than 99.9%, 49.9%:49.9%, 99.9% at 60 GHz and 96.4%, 98.5% at 59 GHz and 61 GHz. In addition, the same NRD guide components except frequency demultiplexer are also designed at wideband operation and achieve broad bandwidth around 5 GHz, 4 GHz, and 3 GHz. In order to improve the computational efficiency, the originally developed two-dimensional full vectorial finite element method is employed for the numerical simulations. This paper demonstrates the detailed implementation procedure of developed evolutionary approaches for the material distribution in the design region of NRD guide devices, comparative study of developed optimization approaches, and proposed highly attributed NRD circuit components for the realization of NRD based high-performance compact millimeter-wave circuit.
