Optimal Design of THz NRD Rat-Race Circuit Using Function Expansion Based Topology Optimization Method With CMA-ES

Rat-race circuit devices are crucial components in the design of THz-wave circuits. Although nonradiative dielectric (NRD) waveguides having simple structures and extremely low loss are promising platforms for THz-wave circuits, it may difficult to realize conventional rat-race devices in NRD platfo...
