A magneto-quasi-static surface formulation to calculate the impedance of 3D interconnects with arbitrary cross-section

This paper presents a surface formulation to calculate the impedance of 3D interconnects with arbitrary cross-section under the magneto-quasi-static assumption. The proposed formulation combines the 2D differential surface admittance operator for conductors of arbitrary shape with the electric field integral equation to calculate the impedance. The proposed formulation avoids any volumetric discretization of the conductors, which results in faster computation times and lower memory consumption compared to other methods.
