2.4 A 1 GHz parallel-plate transmission line consists of 1.2-cm wide copper strips separated by a 0.15-cm thick layer of polystyrene. Appendix B gives µe = Ho = 4x ×

10-7(H/m) and oc= 5.8 x 107 (S/m) for copper, and Er= 2.6 for polystyrene. Use Table 2-1 to determine the line parameters of the transmission line. Assume that u = µo and oz 0 for|polystyrene.
