摘要: Abstract The paper presents a manufacturing study of three-dimensional (3D) diamond electromagnetic band-gap (EBG) structures with new system. EBG made from dielectric composites alumina-slurry 55 vol% Al 2 O 3 powder were fabricated by means stereolithography (SL) and gelcasting samples the structure alumina-resin (before sintering) that alumina-air (after investigated. lattice constant was 12 mm, while in 〈110〉 direction appeared at 9.00–12.00 GHz, which agreed fairly well simulation results based on finite element method (FEM) Ansoft HFSS.
