[BC] Wave lengths

[Milton R. Holladay Jr.]

As I was about to say before accursed cursor spasticity struck:
Visualize the conductors of coax as two infinite strings of little series
inductors, and the dielectric as an infinite number of little shunt
capacitors connected across them in a ladder arrangement, ladder line being
the epitome' this. Is it starting to look like a delay line yet ?
