Thin nano-particle conductors of the order of micrometer in thickness are typical for printable electronics technology. A two-dimensional (2-D) eigenmode solver based on Jacobi-Davidson algorithm is applied to printable transmission lines to evaluate the conductor loss. Efficient preconditioning for the interior solver is utilized to treat poorly-conditioned complex system matrix arising from the fine discretization of conductors required to accurately model the conductor loss. The solver can be used to determine the required layer thickness and conductivity for a desired line loss as well as to the analysis of wide-band material characterization results. The approach is used to determine actual material parameters from wide-band extraction results for inkjet-printed dielectric and nano-silver conductor.
