Reducing Electromagnetic Interferences on Power Planes of High-Speed Circuits by means of a High-Impedance Electromagnetic Surface

In this paper, a stop-band filter realized by a high impedance surface for reducing electromagnetic interference from printed circuit boards is studied. Starting from an existing high impedance surface, Design of Experiments techniques and numerical simulations were employed to analyze the effect of its geometrical parameters on the desired forbidden band-gap of the filter. Finally, an improved high impedance surface is proposed.
