An Investigation of Modal Characteristics and Discontinuities in Printed Circuit Transmission Lines (Microstrip, Galerkin, Singular, Integral, Coupled-Mode)
… a number of topics are considered that concern printed circuits and printed circuit discontinuities. First, propagating and evanescent modes of a shielded microstrip are calculated using the spectral Galerkin technique. The characteristic impedance and field configurations of these modes are …

Shape Approximation of Printed Images in VLSI Design
… still lead to undesirable irregularities in printed images on wafer. These post-lithographic distorted shapes are of interest for electrical extraction of printed circuits. To reduce processing time, it is desirable to approximate the resulting two-dimensional contours with simpler polygons. …
