## Abstract Lifeline systems, such as water distribution and gas supply networks, usually cover large areas. For these systems, seismic design is always a difficult problem because of the complexity of largeβscale networks. In this paper, a topology optimization technology for lifeline networks is

Topology optimization can be seen as optimizing a distribution of small topological elements within a domain with respect to given specifications. A numerical topology gradient (TG) algorithm is applied in the context of electromagnetism for optimizing microwave devices, computing the sensitivity on
reflections of y18 to y24 dB were observed for cases 1 and 2, and y16 and y20 dB for case 3. Our results indicate that the effect of RF microwave loss of the metal structures for the three cases above is clearly negligible. ## III. CONCLUSION In summary, a TirAurTi structure was found, by compari
