Abstract :
The effects of permittivity, w/h ratio, and pulse duration on the distortion of Gaussian pulses are investigated. For w/h=1 and in /sub r/<9.7, the pulse distortion becomes independent of the w/h ratio. Using a unified dispersion model, the distortion of a Gaussian pulse on a composite substrate and a suspended substrate is examined. In the case of the composite substrate pulse distortion can be controlled by proper selection of the w/h ratio and the thickness of a low-permittivity substrate. The fractional change in in /sub eff/ can provide a measure for characterizing the pulse distortion.<>
