Fig. 5: Electric field of flat coax.
From: Surface loss calculations and design of a superconducting transmon qubit with tapered wiring
Plot of the surface electric field for a flat coax for both the metal surface (black) and substrate (blue), obtained by numerical simulation (dots) for the zero thickness limit. The solid lines (green, red) are predictions from Eqs. (15) and (16) and fit well the numerics. Parameters are \(\overline{r}=10\,\mu {{{\rm{m}}}}\) and R = 100 μm.
