This paper presents the development of highly integrated millimeter waves function in multilayer LTCC and Liquid Crystal Polymer technology. Both ceramic and organic technologies are candidate of choice for the 3D integration, following the system-on-package concept, of compact, low cost, millimeter-wave high data rate wireless systems. Compact and easy-to-design passive functions such as direc...

background : in anterior endodontically treated teeth a better esthetic can be achieved by using all-ceramic post -core restorations instead of metal post systems. maximum retention and fracture resistance of the post are the criteria upon which selection of a post system is based. the aim of this study was to evaluate the fracture resistance and retention of two all-ceramic post and core syste...

The aim of this paper is to introduce a new family low-profile resonators and filters that achieve high performance low insertion loss without the need for post-production tuning. resonator termed ceramic-element based distributed consists matrix subwavelength-length ceramic posts connected in inter-digital fashion top bottom ground planes. Such disposition elements beneficial two main reasons....

This paper presents a novel approach to design a parametric RF stop band pass filter based on Low Temperature Co-fired Ceramic (LTCC) Technology. The LTCC technology enables to miniaturize and development compact structures using not only the standard xy-planar circuit dimensions but also the zheight dimension. The proposed filters topologies are based on a stripline loaded with one or several ...

Electronics packaging evolution involves both architectural and technology considerations. In this paper, we present the design and measurements of Single-Input-SingleOutput (SISO) dual-band filters operating at ISM 2.4-2.5 GHz and UNII 5.15-5.85 GHz frequency bands, using the novel ”dual behavior resonators” technique. The filters have been fabricated using Low Temperature Co-fired Ceramic (LT...

For the preparation of the coating the CNTs were dispersed in a 30 wt% solution of 3MBP-dca in deionised water by sonication. The resulting black slurry was filtered by vacuum filtration and the black residue in the filter was washed with 50 mL of ethanol to remove excess IL. The residue was subsequently placed in ceramic crucible and thermally treated in a furnace under constant argon flow to ...
