Field Solution for a Thin‐Film Superconducting Strip Transmission Line

摘要: By using Londons' equations, the two‐fluid model, and classical skin effect for normal component of current, a sinusoidal wave solution is found superconducting transmission line. This gives slow mode propagation which dependent on ratios dielectric film thicknesses to penetration depth. At low temperatures frequencies where losses are low, velocity dispersionless even though there electric field in direction propagation. The solutions attenuation vary continuously as one passes through critical temperature into state. interpreted terms lumped circuit characteristics.
