Claim Text:
1. A printed circuit board, comprising: a plurality of non-conductive layers with conductive or signal layers in between; a first conductive via traversing the plurality of non-conductive and conductive or signal layers; a second conductive via traversing the plurality of non-conductive layers and conductive or signal layers, the second conductive via located substantially parallel to the first conductive via; and a magnetic reflective electrical passive element extending perpendicular to and coupled between and from the first conductive via to the second conductive via, wherein the magnetic reflective electrical passive element is configured and positioned to redirect a source electrical signal through the second conductive via and is embedded within a selected layer at a first depth in the printed circuit board, wherein the first depth, length, and width of the magnetic reflective electrical passive element are selected, based on a characterized electromagnetic propagation of the source electrical signal through at least the first conductive via, to reflect an incident electromagnetic wave to achieve a particular desired positive or negative electromagnetic interference to enhance or diminish the source electrical signal in the first conductive via; the first conductive via is coupled to a first signal trace in a first layer and a second signal trace in a second layer, wherein the source electrical signal flows from the first signal trace into the first conductive via, and the magnetic reflective electrical passive element has a width that is between a diameter of the first conductive via and twice the diameter of the first conductive via.
