Suppose the voltage waveform shown in Fig. 2-45 was observed at Suppose the voltage waveform shown in Fig. 2-45 was observed at the sending end of a 50-??transmission line in response to a step voltage introduced by a generator with Vg = 15 V and an unknown series resistance Rg. The line is 1 km […]
Suppose the optical fiber of Example 8-5 is submerged in water
Figure 4-34(a) (P4.47) shows three planar dielectric slabs of eq Figure 4-34(a) (P4.47) shows three planar dielectric slabs of equal thickness but with different dielectric constants. If E0 in air makes an angle of 45 _ with respect to the z-axis, find the angle of E in each of the other layers.
Such a line is called a distortion less line because Such a line is called a distortion less line because despite the fact that it is not lossless, it does nonetheless possess the previously mentioned features of the loss line. Show that for a distortion less line,
