Application of 2D structures that present electromagnetic band-gaps (EBG's) to signal integrity issues has been a subject of interest in the last decade. An important problem to be solved is to match the EBG and the spectrum of the noise. This can be done, among others, by using materials with prescribed dielectric constants which is usually of high value and consequently a costly solution. A cheaper...
The problem of parallel-plate noise mitigation pertaining to signal integrity in high speed digital and mixed-signal circuits is tackled. A parametric study of a proposed planar, periodic, metal structure embedded in an inhomogeneous parallel-plate waveguide is performed by full-wave electromagnetic simulation. Results demonstrate that the proposed solution meets the requirements of the problem. Detailed...
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...
Numerical study of a high impedance surface built in microstrip technology by using periodically arranged elliptical patches, grounded through one to four vias is presented. The effect of the variation of the number of vias manifests in different manner on the electromagnetic band gap aperture and position, as results from the parametric study in function of the patch dimensions and diameters of the...
