MODELING THE WAVE PARAMETERS OF A NARROW SLOTTED TRANSMISSION-LINE BASED ON A SUPERCONDUCTING FILM

An analytical expression for calculating the wave parameters of a narr ow-slot transmission line is found in the quasistatic approximation. A two-fluid model is used for analyzing processes in a superconducting film of thickness comparable to the London penetration depth. The wave parameters of the slotted line are calculated under assumptions about the current distribution near the edges of the slot which are analogo us to those used previously for analyzing microstrip and coplanar line s.
