Correlated electron systems, particularly iron-based superconductors, are extremely sensitive to strain, which inevitably occurs in the crystal growth process. Built-in strain of this type has been proposed as a possible explanation for experiments where nematic order observed at high temperatures corresponding nominally tetragonal phase superconductors. Strain is assumed produce linear defect ...

Analytical models for passive linear structures, like metallic traces, vias, are proposed simulations at the package and Printed circuit board (PCB) levels. In method, traces modeled based on transmission line theory, whereas vias described by parallel-plate impedance several equivalent circuits elements. The can be applied to efficiently simulate composed structures. Several scenarios analyzed...
