A lossless line having an air dielectric has a characteristic impedance of 100 Ohms. Another line that is identical in dimensions to the air line is fabricated with the air displaced by a dielectric material have an \(\epsilon_{r}\) value of 4. Both lines operate at 200 MHz and ZL = 200 %u2013 j100 . For each line use the applicable equations to find: (a) s (the standing wave ratio) and (b) Zin, if the lines are 0.5 m long.
