In order to realize low-dispersion and large group index, an objective function to be optimized is expressed by the weighted sum of the objective functions for the desired group index and the low-dispersion property, and weighting coefficients are updated through the optimization process.}, pages = {670--676}, title = {A Study on Optimization of Waveguide Dispersion Property Using Function Expansion Based Topology Optimization Method}, volume = {E97.C}, year = {2014}, yomi = {ツジ, ヤスヒデ and ヤスイ, タカシ and ヒラヤマ, コウイチ} }
