S. Safavinaeini et al., STUDIES OF EDGE CURRENT DENSITIES IN REGULAR AND SUPERCONDUCTING MICROSTRIP LINES OF FINITE THICKNESS, IEE proceedings. Part H, Microwaves, antennas and propagation, 140(5), 1993, pp. 361-366
Distributions of the current and the surface fields close to the corne
rs of a conducting strip with rectangular cross-section are investigat
ed by an accurate and efficient moment method. The strip is made of ei
ther a normal conductor or a superconducting material. Based upon this
study, a simple graphical procedure for a rough estimation of the fin
ite maxima of the current densities at the edges (corners) is presente
