[tex]\alpha =\frac {\omega \epsilon \prime \prime} {2} \sqrt {\mu \epsilon \prime} [/tex](adsbygoogle = window.adsbygoogle || []).push({});

My question is what exactly does the [tex]\epsilon \prime \prime[/tex] term signify??

I see sections of my notes that say [tex]\epsilon \prime \prime << \epsilon [/tex], but what is it?

I mean when I am trying to find the attenuation constant and the material happens to be a low-loss dielectric and you are given the actual permittivity [tex]( \epsilon )[/tex] I don't know what to do with the [tex] \epsilon \prime \prime[/tex] term. It's the only value I don't know in the problem?

I would REALLY appreciate any help on this because I really need to understand this before my exam on Monday.
