Implement a simple computer code or Excel workbook to compute the values of R, L, G, C, a (attenuation constant: Equation 2.25a in the Ulaby textbook), B (phase constant: Equation 2.25b in the Ulaby textbook), velocity of propagation (Equation 2.33 in the Ulaby textbook), and Z. (Equation 2.29 in the Ulaby textbook) for a coaxial transmission line and two-wire line (not the parallel-plate). (see Tables 2-1 & 2-2 in your textbook). The lines are not lossless: use the general-case formulas. Note that the material permeability is u = Holly, where the free-space permeability is Ho = 411 x 10-7. For non-magnetic materials (most materials) the relative permeability is Hy = 1. As a result, u = He = Ho. Refer to Eqn. 2.6 for the explanation of Rs Also note, similarly, that the permittivity is = ., where the free-space vity is , = 8.854 x 10-12 and the relative permittivity is e(the relative permittivity is l in free space, but is generally larger than 1 in other materials) Table 2-1 Transmission-line parameters R', L', G', and C' for three types of lines.
