Frequently, it … WebThe notion of vacuum impedance was introduced in late 1930’s by Schelkunoff1in the study of wave prop- agation. It is defined as the amplitude ratio of the electric and magnetic fields of plane waves in vacuum, Z 0= E/H, which has the dimension of electrical resis- …

Webeling wave coming in at very early times, hitting the junction around t=0 (obviously all parts of the wave can’t hit the junction at the same time). We would like to know what the wave looks like at late times. Let us write the amplitude of the wave as ψL(x,t) to the left of the knot at ψR(x,t) to the right of the knot. ψ(x,t)= ˆ ψL(x,t ...
