My best coil was designed on the back of an envelope (literally!)
over a cup of tea during a 20 minute tea break. I resonated at
exactly the frequency it was designed to do so and, most crushing of
all for the relativistic afficionados, was designed using simple
lumped parameters. I did make room for consideration of losses due to
skin/proximity effects but a decision to spacewind with a 1:1
wire/space ratio plus a suitable wiresize for its (lowest) frequency
of operation based on a simple guideline kept the quantum genie
firmly corked up in its bottle.
