Precise Crosstalk Assessment in Complex Nanointerconnects via a Family of Unconditionally-Stable Nonstandard Time-Domain Algorithms

Abstract

A class of nonstandard locally one-dimensional finite-difference time-domain schemes is developed in this paper for the accurate characterization of crosstalk and intermodulation distortions in complicated nanostructured interconnects. The novel 3-D methodology introduces a general curvilinear discretization to consistently treat the rapidly varying frequency-dependent behavior of these lossy materials. In this way, the resulting high-order forms minimize the artificial dispersion and dissipation errors of usual approaches and guarantee the unconditional stability of far shorter simulations. Numerical results, compared with measurement data, verify the assets of the proposed technique via the study of various fabric/epoxy devices with nanocomposite media.
