Abstract
Apparatuses and methods associated with shield lines, and/or complementary decoupling capacitors and/or electromagnetic absorbing materials are disclosed herein. In embodiments, an apparatus may include a substrate having a ground plane; and a first and a second transmission line disposed on the substrate. Further, the apparatus may include a shield line constituted with electromagnetic absorbing material disposed between the first and second transmission lines and not coupled with the ground plane. In embodiments, the substrate may further include a power plane having a plurality of edges and a plurality of spacing; a plurality of decoupling capacitors disposed on the power or ground plane; and electromagnetic absorbing materials adhered to the plurality of edges and disposed in the plurality of spacing. Other embodiments may be described and/or claimed.
