Kinetic inductance of superconducting nanostrips with turns

Kinetic inductances of superconducting nanostrips with a meander pattern are theoretically investigated based on the London model, and effect current crowding at turns is considered. The complex approach developed for analytical investigation kinetic inductance thin $d<\lambda$ narrow $w\ll \lambda^2/d$ strips, where $d$ strip thickness, $w$ width, $\lambda$ penetration depth. We show that distribution in $wd\ll\lambda^2$ identical to normal conducting $wd\ll\delta^2/2$, $\delta$ skin depth, dependence nanostrip geometry resistance. Effects edge defects strips upon also
