摘要

本文对具有椭圆腔的近零指数(NZI)壳结构进行了计算设计和分析，该结构可以在各向同性源激发下提供定向辐射特性。可选择的策略，如内部腔的几何形状，使用金字塔纹理，并选择合适的材料特性，用于创建对称和非对称梁。

Computational Design and Analysis of Beam-generating Shells with Elliptical Cavities Made of Near-Zero-Index Materials

We present computational design and analysis of near-zero-index (NZI) shell structures with elliptical cavities, which can provide directional radiation characteristics when excited by isotropic sources. Alternative strategies, such as geometric shaping of internal cavities, using pyramidal textures, and selecting suitable material properties, are employed to create symmetric and asymmetric beams.
