| Popis: | Two-dimensional columnar structures as well as honeycomb hole structures for electromagnetic bandgap (EBG) applications in the microwave range are generated by vacuum moulding of a specially designed wax feedstock of high alumina loadings into a polyethylene wax mould. Its counterpart, honeycomb hole structures, are produced by usage of silicone rubber moulds. The structured ceramic parts with an aspect ratio of about 4 show an Archimedes-type density of about 97.0%. Damages on the sample's structures that could occur during demoulding/debinding were minimized by the adjustment of the mould material to the feedstock system, the implementation of a suitable moulding technique and an optimisation of the thermal wax burnout process. The processing technique describes a route to obtain ceramic structures of high precision with a minimum of technical requirements. |
