need help with question 3 ( question 2 for reference )
3) For the cable in problem 2) now consider it to be lossless (i.e. perfect conductors and filled with a dielectric material
2) Consider a coaxial cable with the outer conductor radius of 8 mm and inner conductor radius of 4 mm. Assume a 100 MHz sign
3) For the cable in problem 2) now consider it to be lossless (i.e. perfect conductors and filled with a dielectric material of ε,-3 and σ-0 S/m). (a) Determine a, B, up and Zo for the line. (b) If the line is terminated by a loading impedance Zt.-(30-j70) 2, find the reflection coefficient at the load, the standing-wave ratio on the line, the position of the voltage maximum nearest the load, and the position of the current maximum nearest the load.
2) Consider a coaxial cable with the outer conductor radius of 8 mm and inner conductor radius of 4 mm. Assume a 100 MHz signal. (a) Calculate the parameters R'. L, G' and C" assuming that the conductors are Cu and the space between them is filled with a dielectric material of Er-3 and ơ-103 S/m. (b) From the parameters in (a) determine α, β, up and Zo for the line. (c) How far would a signal travel in this line before its amplitude drops to l/e of its original value? (d) From the parameters could we approximate this cable as lossless? (e) At 10 GHz is it a better approximation for a lossless cable?
