ECE 329 Homework 10 Due: Tue, April 1, 2008, 5PM 1. Using Table 5.2 from the text determine: a) C (capacitance per unit length), L (inductance per unit length), and Z o ± L C (characteris- tic impedance) for a pair of parallel cylindrical wires embedded in free space having the dimensions d =0 . 5 cm and a =0 . 05 cm. b) Inner radius a of a pair of coaxial cylindrical conductors embedded in free space if the outer radius

Unformatted text preview: b = 3 inches and the characteristic impedance Z o ≡ ± L C is 50 Ω . 2. Consider the lossy form of telegrapher’s equations-∂v ∂z = L ∂i ∂t and-∂i ∂z = C ∂v ∂t + G v. Assuming a voltage solution v ( z, t ) = e-αz cos( ωt-βz ) , express a) α and β in terms of L , C , and G , b) the corresponding current solution i ( z, t ) . 1...
