A metamaterial based solution for parallel-plate noise reduction in power planes of digital and mixed-signal fast circuits is presented. The solution consists of embedding a periodic patterned surface between two dielectric layers and two metal planes. The novelty stems from the shape of the metal motif of the patterned surface of the unit cell. In each unit cell nine vias connect the metal patch...
A novel geometry of unit cells relying on printed technology and featuring full dispersion diagram (DD) exhibiting an unusual large number of electromagnetic band-gaps (EBGs) is proposed. The printed patch consists of a filter-like geometry, meandered around the symmetry center of the unit cell and connected to the ground plane by three aligned vias, locally increasing the loading inductances; the...
