  • ELECTROMAGNETIC BAND GAP DEVICE
    Publication number: 20150009084
    Abstract: An electromagnetic band gap device is disclosed that includes a dielectric support of which one face is metallized and of which a second face includes a plurality of non-adjoining conducting elements. Several conducting elements are linked together pairwise by a resistive element in the electromagnetic band gap device. At least two of the conducting elements are electrically insulated from one another and at least two resistive elements exhibit a different resistance value.
