Abstract
The dispersion and attenuation characteristics of conductor-backed cop lanar transmission lines with finite-width ground metallizations are s tudied in the frequency range up to 1 THz. The finite-difference time- domain (FDTD) method is used for analysis. Open boundaries are describ ed by means of Berenger's perfectly matched layer, The results are com pared to electrooptic measurements, They show that introducing ground metallizations of finite width causes distinct changes in attenuation and dispersion characteristics.
