The dimensions of a certain coaxial transmission line are a = 0.8 mm and b = 4 mm. The outer conductor thickness is 0.6 mm, and all conductors have σ = 1.6 × 10⁷ S/m.

(a) Find R, the resistance per unit length at an operating frequency of 2.4 GHz.

(b) Use information from Sections 6.3 and 8.10 to find C and L, the capacitance and inductance per unit length, respectively. The coax is air-filled.

(c) Find α and β if α + jβ = √jωC(R + jωL).
