A two-dimensional (2-D) analytical approach, based on the transmission-line modelling of metallo-dielectric electromagnetic bandgap (EBG) structures, is presented. This analysis technique is exploited to investigate the band diagrams of the EBG structures embedded in a parallel-plate power distribution network; an arrangement which is commonly used for global suppression of switching noise in high-speed circuits. Complex 2-D Bloch analysis is utilised in the proposed methodology to obtain the 2-D attenuation diagrams corresponding to the 2-D dispersion curves, in a matter of few seconds. The insertion loss information extracted from these attenuation diagrams is employed in predicting the efficiency of the noise suppression method
