WebSolution: At the end of the line the total current is zero, so that I+ +1- = 0 and so = I-=-1+. (2.66) The forward- and backward traveling voltages and currents are related to the characteristic impedance by Zo = 7+/1+ = -V-/1_, (2.67) + Note the change in sign, as a result of the direction of propagation changing but the positive reference for … Webgation, and c+ and c-are the unnormalized forward and backward amplitudes of the modes. We call these propagating modes traveling waves. The power of the simplifications we have required is that the total field due to the traveling waves in the transmission lines we use can be described by the two complex quantities c+ rubber stator screw pumpWebBackward traveling wave properties The BTW accelerator structure combines the advantages of traveling waves and standing waves. The forward TW electrically coupled on-axis structure (the classical “disk- loaded waveguide”) is remarkable for its good adaptation and short filling time. rubber stickers for furniture
