13. The parameters of a certain transmission line operating at 6 × 108 rad/s are L=0.4μH/m, C=40pF/m, G=80Ms/m and R-2002/m. (a) Find propagation constant, attenuation constant, phase constant, wavelength and characteristic impedance (b) If a voltage wave travels down 20m down the line, what percentage of the original wave remains and by how many degrees it is phase shifted. 14. 15. A 100MHz voltage source drives the series combination of an impedance Zg = 25+ j25 and a lossless transmission line of length 1/4. The line characteristic impedance is 500 and is terminated in a load impedance. a) Determine the load impedance value required to achieve a net impedance of 5002. (b) If the inductance of the line is 1 μH/m, determine the line length in meters. An air filled rectangular waveguide operates at 1GHz and has its dimensions of 5cm x 2cm. Check whether TE21 mode propagates or not.
