Miniaturization of normalstate and superconducting striplines
Abstract
The properties of normalstate and superconducting striplines are calculated as a function of miniaturization. For normal conductors the ReuterSondheimer theory is applied in order to account for the effects of finite film thickness and mean free path. For superconductors the MattisBardeen theory is used in order to include effects due to the energy gap. Calculations for three example conductors, copper at 295 K and 4.2 K and niobium at 4.2 K, examine the attenuation, dispersion, and characteristic impedance of striplines as a function of frequency and dielectric thickness. Simulations of pulse transmission are used to evaluate the utility of the example striplines for highspeed digital applications.
