Abstract

The effects of planar transmission line dispersion, as well as dielectric and ground plane losses, on the propagation of pico-second electric pulses are investigated. For this purpose, the Spectral Domain Approach (SDA) and Fast Fourier Transform (FFT) are used, to operate in the frequency and time domain, respectively. It is observed that the transmission line dispersion is the main cause for distortion of the pulses, while the material losses are mainly responsible for signal attenuation. It is also observed that the dispersive nature of the transmission line can be used with advantage, through careful choice of the line geometry and composition, to reshape asymmetrical pulses, and to compress wide electrical pulses. The results of this study find applications on quasi-optical circuits and short optical pulse generation.
