| 摘 要： | 基于介质圆柱电磁散射理论和等效介质理论，导出了金属柱微粒-电介质复合材料的等效相对介电常数的表达式。数值结果表明：入射波频率低于某一频率或金属柱掺料的体积分数增大到一定数值时，复合材料的等效相对介电常数实部会变为负数。

| Abstract: | Based on the electromagnetic scattering theory of dielectric wire and effective medium theory, the formula of the effective dielectric constant of metal wire-dielectric composites is derived. Numerical results reveal that effective dielectric constant becomes negative when incident wave frequency is below some frequency or the metal concentration is more than some value. |

| Keywords: | Metal wire-dielectric composite Effective dielectric constant Effective medium theory |
