We propose a technique to build artificial anisotropic dielectrics by using periodic insertions of a homogeneous material in a homogeneous substrate, characterized by a different dielectric constant. We calculate the effective dielectric constants corresponding to the three principal directions by means of dispersion diagrams associated to the periodic structure. The proposed method to realize low...
A 2D, volumetric (i.e., non-planar), structure consisting of two dielectric layers, loaded by various metal inclusions on multiple-periodic grids and closed by two confining metal planes is introduced in view of advanced dispersion engineering related applications. Full-wave simulation has been used to demonstrate that, for axial propagation, the structure presents (i) a large electromagnetic band-gap...
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...
