As an electrical engineer, you are required to construct a bounce diagram for a lossless type of transmission lines as in Figure 3.1 to be operated in a frequency, ??=1 GHz. The transmission line is constructed as two parallel wires (Figure 3.2) with diameter, ??=2?? (unit in mm) and separated from center to center by distance, ?? (unit in mm). The relative permittivity, ???? is 2, and permeability, ??=????. The length, ?? of the lines is 100 m. Given ????=0.5????,...
