I`m guessing Art`s point was that all circuit elements are impure. A
resistor has lead inductance and is shunted by self-capacitance, etc.
That is not the only cause of anomaly. Size in terms of wavelength means
that radiation becomes significant in some cases, especially in
structures designed to radiate.

If there is radiation from a circuit, ordinary circuit analysis does not
apply say King, Mimno, and Wing, all Ph.D.`s at Harvard teaching U.S.
Army and Navy officers in the Graduate School of Engineering during
WW-2.

Exactly Richard,
To have an iductor you must have wire length and if it is part of a
circuit
it therefore radiates. No messing around with theoretical back SWR to
confuse the issue or mythical components. The real world says
inductance is just part of many things that come as part of it
including length which means radiation and capacitance which means
phase angle change.
In the case of radiation it must beconsidered as a 'loss' when solving
equations. The so called experts are really screwing around to provide
a platform to show off there learned minds instead of sticking to
basics
