I have questions:(adsbygoogle = window.adsbygoogle || []).push({});

1) What is the limitation of using:

[tex]\vec H ( \vec r, t) =\frac 1 v \nabla \times \vec E(\vec r, t)\;\hbox { where }\; v= \frac 1 {\mu \epsilon}[/tex]

I know for this formula to work, the medium has to be charge free. I want to know in what other cases I cannot useEto findB. I think theEhas to be time harmonic wave which mean it is a sine wave of certain frequency [itex]\omega[/itex]. Any other limitation?

2) What is the limitation of using the formula in findingHof TEM wave in a medium ( lossless, lossy or practical good conductor )?

3) TEM wave only sayEandBare perpendicular to each other and both perpendicular to direction of travel. Is plane wave part of the TEM wave?

Thanks

Alan
