In this contribution, an enhanced 3-D differential surface admittance operator is proposed, facilitating accurate modeling of piecewise homogeneous cuboidal objects. By exploiting the analytical properties of entire-domain basis functions, material interfaces are effectively eliminated from the formulation, leading to a reduction in the number of unknowns without compromising the accuracy of the operator. After a validation of the novel approach, its effectiveness is demonstrated through the analysis of the impedance responses of on-chip interdigital capacitor structures.
Bridging the AC Non-Equilibrium Green’s Function Formalism and Transmission Line Models for the Analysis of Nanointerconnects
The unfavorable scaling of Cu interconnects at nanoscale dimensions has prompted the search for alternative materials. To model electron transport in these novel nanointerconnects, both
