or FAQ depending on how you look at it... I should probably repeat this
regularly on here.

This newsgroup should NOT be used as a reference source for concepts or
equations regarding fields, waves, transmission lines, or other physical
phenomena. Please consult published text books and peer reviewed journals
for analysis of technical questions. The regular contributors in this group
have a wide variety of misconceptions and erroneous views which they
frequently throw in as if they were well known facts.

On the lighter side, it can be fun now and then to throw them a simple
problem and watch them swarm around like a kicked hornet nest.
