Abstract
In this paper, the influence of ceramic slurry sedimentation on microwave transmission performance of diamond EBG structure was studied. Standard dielectric pillar samples and diamond EBG structure were fabricated using a combination of stereolithography (SL) and gel-casting with alumina. The alumina slurry sedimentation resulted in an obvious change in the dielectric constant of the bottom and the top of the samples when gel time was controlled between 2 to 10 minutes. Microwave transmission performance of diamond EBG structure can be affected also by controlling gel time to form gradient dielectric ceramics. The research can be used to improve the fabrication precision in gel-casting and the performance of band gap and bandpass of EBG structure by forming gradient dielectric ceramics.
