摘　　要：用高稳定的辛时域有限差分算法(SFDTD)对金属周期孔阵在Ku波段的透波增强特性进行了研究。数值计算了金属板厚度、孔的大小、孔中填充不同折射率的介质和孔阵的周期等物理参数对孔阵透射系数的影响。得出的研究结果表明:金属周期孔阵在Ku波段的透射系数随孔的增大而增大,随孔阵周期的增大而减小,填充高折射率的介质有利于其透射。The transmission enhancement characteristics of metallic hole array are investigated by using the high stable symplectic time domain finite difference method （SFDTD）in Ku-band. The influences of the thickness of metal plate, the size of hole, the refractive index of filled medium, the periodic of hole arrays on the characters of transmission are simulated. The results have shown that the transmission coefficient enhances as the size of hole increases, and reduces along with the periodic of metallic hole array increases. Filling the high refractive index medium is favorable for its transmission.
