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.
Power-efficient Near-field Focusing for Upcoming 6G MIMO Networks
An accurate and efficient near-field intensity shaping method is proposed, capable of reproducing sharp patterns while simplifying the design requirements of the array’s feeding network.
