Modeling and analysis of electromagnetic bandgap structures on power distribution network

Transmission line method (TLM) is applied for analysis of a conventional electromagnetic bandgap (EBG) structure with arbitrary shaped power/ground plane. The fast and accurate modeling by TLM shows the computationally efficient results with respect to full-wave electromagnetic analysis. More-over it is shown that suppression bandwidth of a EBG structure can be easily analyzed by stepped impedance filter and the calculated bandwidth is identical to the measured.
