Application: Microstrip line. A conducting strip with dimensions as shown in Figure 14.34 is located above a conducting surface. The strip is very long and the conducting surface is infinite. Also, ω » d. The strip and surface serve as a transmission line. Calculate assuming perfect conductors:
(a) Speed of propagation of waves on this line.
(b) Characteristic impedance of the transmission line for ω = 10 mm, and d = 0.1 mm.
