Question: A sinusoidal wave on a transmission line is specified by voltage and current in phasor form: V s (z) = V 0 e z e

A sinusoidal wave on a transmission line is specified by voltage and current in phasor form:

Vs (z) = V0 eαz ejβz and Is (z) = I0 eαz ejβz ejφ

where V0 and I0 are both real.

(a) In which direction does this wave propagate and why?

(b) It is found that α = 0, Z0 = 50, and the wave velocity is v p = 2.5 × 108 m/s, with ω = 108 s−1. Evaluate R, G, L, C, λ, and ϕ.
