    STRUCTURAL SHAPE OPTIMIZATION BY ISOGEOMETRIC BOUNDARY ELEMENT METHOD by SUN ShaoHui, YIN ShuoHui

    Published 2019-01-01
    “…In this article IGA-BEM is combined with particle swarm optimization(PSO) to study the shape optimization of two-dimensional linear elastic structure. Compared with the gradient-based optimization algorithms, gradient-free PSO algorithm can avoid the complicated sensitivity analysis process and make the optimization process easier. …”

    Near-Zero-Refractive-Index Structure at Optical Frequencies by Hassan S. Ashour

    Published 2013-01-01
    “…The modal dispersion relation and the power flow were numerically solved for a given set of parameters: dielectric slab thickness, the operating frequency, mode order, and the power flow and extinction in the structure. The real part of the effective refractive index exhibits near-zero values, with small extinction coefficient values. …”
