I added the equation about it here.
I'm stopped since I failed to calculate wave impedence.
Especially, relative permittivity and relative permeability are big obstacles for me to solve.
What I'd like you to do for me is not let me know how to calculate easily(of course, I'd thank you for it),
it would be even very thankful to you if you share me with books addressing this, with book names together.
Thank you for reading my question. I hope you help me.
You have probably seen this but since nobody else has answered at least it is something
http://www.mathworks.com/examples/aa/mw/antenna-ex82816538-wave-impedance
and of course:
https://en.wikipedia.org/wiki/Wave_impedance
The Wiki article has some references and additional info in the "talk; tab that could lead you to someplace more useful.
I hope this helps.
Wave impedance: At a point in an electromagnetic wave, the ratio of the electric field strength to the magnetic field strength. Note 1: If the electric field strength is expressed in volts per meter and the magnetic field strength is expressed in ampere-turns per meter, the wave impedance will have the units of ohms. The wave impedance, Z , of an electromagnetic wave is given by

where is the magnetic permeability and is the electric permitivity. For free space, these values are 4 × 10-7 H/m (henries per meter) and (1/36) F/m (farads per meter), from which 120, i.e., 377, ohms is obtained. In dielectric materials, the wave impedance is 377/n, where n is the refractive index. Note 2: Although the ratio is called the wave impedance, it is also the impedance of the free space or the material medium.
In the following website you find and example and solution to calculate wave impedance.
