I'm having some trouble understanding this module. It would be great if anyone could help.(adsbygoogle = window.adsbygoogle || []).push({});

In a homogeneous nonconduction region where μ_{r}= 1, find ε_{r}and ω if

E=30(pi)e^{[i(ωt-4/3y)]}in z direction

H=0.1e^{[i(ωt-4/3y)]}in x direction

I am to understand that for a homognous nonconduction region D=εE and ε=ε_{r}ε_{0}. However, just equating ε_{r}=D/ε_{0}E doesn't seem right. Judging from textbooks and notes I am assuming i must use Maxwell's eqn's for a homogenous nonconducting region, but I'm not sure where to get started. Similarly for ω i can equate ω=(ln|B/10μ_{0}|+4/3y)/t. But again, I'm not sre that this is right.

If anyone could point me in the right direction that'd be great!
