Talk:Intrinsic impedance

some mistyped formulas

I corrected some mistyped formulas. Unless you are in an anisotropic medium, indexes x and y are not needed in the definition, as E and H are always orthogonal. LPFR 08:39, 23 October 2006 (UTC)

Move to Intrinsic impedance? (currently redirects to here)

• The IEEE Standard Dictionary of Electrical and Electronics Terms (6th ed.) has never heard of electromagnetic impedance.

• I've never heard of it.

• Google has (nearly) never heard of it...

Search term	Google hits
"intrinsic impedance"	39,500
"electromagnetic impedance"	785

...so I propose swapping Intrinsic impedance and Electromagnetic impedance --catslash 10:06, 1 May 2007 (UTC)

Survey - in support of the move

• Support (see above) --catslash 10:06, 1 May 2007 (UTC)
• Support per nom. --Gabbec 19:49, 1 May 2007 (UTC)

Survey - in opposition to the move

OK, I've done it, and without giving much opportunity for comment; but it's only a move/rename and easily reverted in the event of disagreement. --catslash 21:05, 1 May 2007 (UTC)

Distinction between electromagnetic and electrical impedance

The article says Electromagnetic impedance is not to be confused with electrical impedance. This distinction is new to me, and I can't see that E/H is somehow different to V/I. ...Unless it means to say that the intrinsic impedance should not be confused with the resistivity of the medium, which might be considered a valid point. So if it means what it says, then I reckon it needs a citation, and otherwise it needs clarifying --catslash 10:24, 1 May 2007 (UTC)
