On differences between a straight and curved transmission line

Electrical impedance measurements were performed on a straight and curved transmission lines with the same physical dimensions and the same driver. Diameter of the transmission lines was 15 cm and physical, effective length 2 meters. It was found out there are some major differences in the impedance frequency response. Curved shape of a transmission line generally contributes to dampening of the response curve over the entire frequency range, without necessity to use dampening materials. Acoustical impedance of a curved transmission line was discussed and corrections of the straight transmission line model were proposed.
