Coaxial Waves

words: Walter F. Smith, 11-30-11

tune: Jingle Bell Rock

 

1. If you want a cable that’s great,
Then you should choose RG58!
It has capac’tance one hundred “puff”
Per meter– That’s clearly enough!

2.Combine it with inductance two hundred five-oh
Nanohenries per meter, now watch the waves go!
Zippin’ and zappin’ at twice the speed c,
Divided by three!

Bridge:
When it’s wave time, you can save time
By using this simple rule:
That the V-wave is like the E-wave
Of light in a vacuum, ain’t that cool?

Giddy-up, current times L-naught (I think)
Moves like the B behaves!
Swing and wiggle in cylindrical sync –
That’s coaxial waves!


 

3. The ratio of voltage to current is just
Root L-naught by C-naught, as we have discussed.
So, an infinite cable, though it sounds bizarre,
Feels like a 50-ohm R!

Bridge:
Let us all kneel before Paul Neill,
And Carl Conselman as well.
The correct plug’s a bayonet plug—
The BNC connector’s totally swell!

For left-moving waves, the I’s and the V’s
Are one eighty degrees out of phase  
Swing with anti-symmetrical ease –
That’s coaxial
That’s coaxial
That’s coaxial waves!
