| Abstract: | A processing procedure was proposed to fabricate electromagnetic crystals using stereolithography (SL) and gelcasting system.The electromagnetic crystals were made from alumina-slurry dielectric composites.The SEM photograph of ceramic sample showed that alumina ceramic grain was homogeneous.And their microwave properties were researched in the range 8～13 GHz.The periodvarying diamond EBG structures were obtained by stretching lattices in the direction <100>.It is found that the period-varying diamond EBG structure,compared with the same dimensional period diamond EBG structure,have some regular changes. |
