In this contribution, we propose a novel approach to rigorously model interconnect structures with an arbitrary convex polygonal cross-section and general, piecewise homogeneous, material parameters. A full-wave boundary integral equation formulation is combined with a differential surface admittance approach, invoking an extended form of the numerically fast Fokas method to construct the pertinent operator. Several examples validate our method and demonstrate its applicability to per-unit-of-length resistance and inductance characterization.
Valley filtering in 8-Pmmn borophene based on an electrostatic waveguide constriction
Materials with tilted Dirac cones, such as 8-Pmmn borophene, are being explored for valleytronic applications as the tilting direction is different for nonequivalent valleys. In
