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????,...
Does changing the frequency value (between very low and very high frequencies) will affect the values in the bounce diagram? Explain your answer with suitable equation. (5 marks)
a) The magnetic field intensity of a uniform plane wave in a conductor (?? =????,??=????) is ????⃗=20??−12??cos(2??? ?? + 12? )??⃗?? mA/m. Calculate the conductivity,?? value and the corresponding ???⃗ field if ??=106 Hz. (5 marks)
