A method of determining characteristics for electromagnetic shielding for a signal interconnect is disclosed. The electromagnetic shielding is to comprise a shielding dielectric layer and a shielding conductive layer. The method includes determining a set of harmonic frequencies associated with an operating frequency of a signal to be transmitted via the interconnect, identifying a dielectric material based on a loss tangent of the dielectric material and the set of harmonic frequencies, determining an expected appreciable electromagnetic field generated by a transmission of the signal, and determining a maximum extent of the expected appreciable electromagnetic field from the interconnect. The method additionally includes determining a dimension for the shielding dielectric layer based on the maximum extent, simulating electromagnetic characteristics of the interconnect and the shielding dielectric layer based on the identified dielectric material and the dimension, and verifying an operation of the interconnect and the shielding dielectric layer.
