Abstract: A printed circuit board (PCB) is provided comprising a plurality of non-conductive layers with conductive or signal layers in between. The PCB includes a first conductive via traversing the plurality of non-conductive and conductive or signal layers as well as 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. An embedded electro-optical passive element is also provided that extends perpendicular to and between the first conductive via and the second conductive via. The electro-optical passive element embedded is located within a selected layer at a first depth in the printed circuit board, wherein such first depth is selected to reflect an incident electromagnetic wave back into the printed circuit board to enhance or diminish an electrical signal in the first conductive via by creating a positive or negative electromagnetic interference.
