Characteristic Impedance

Yes and no. I suspect you are asking a homework question, and that you have not asked all of the question.

Nonetheless, I will point you in the right direction. The rest is up to you.

If there are no conductors present (you get the approximate answer if there are only really bad conductors), you can express impedance as the product of the absolute magnitudes of the E field and the H field. Of course, you can always relate H to B. Now, if you are in free space (or anything approximating that), you can reduce that to an expression for the characteristic impedance where

Z₀ = √(μ₀/ε₀), but you should recognize that from Maxwell's Equations, n'est ce pas?

it is impedance and how can be get an impedance by multiplying B and H? B is analogous with current and H is somewhat similar to E so it is more reasonable to divide them rather than multiplying.. best regards..

You are, of course, correct. E/H. May a thousand sowbugs in full rut crawl up my nares.

namely the answer is E/H ??? excuse me but i couldnt get the answer real answer..

How are you trying to work this? What textbook are you using? By the way, we don't do homework on here. I've pointed you in the right direction, but you've got to do this stuff yourself.

this is not homework , a professor had asked us this question and i still lack the answer..(googling is not enough)

So, what E&M textbook do you use?

Anyway, I assume you must know a bit in order to even be asked this question.

Here's one view. Here's another.

excuse me but I need a simple expressed answer, Do we have any chance describing Char. İmp as function of B and H in a formula? I am not telecommunication engineer, The fact is İ am power engineer but İ wonder how can be it expressed by way of these two, Can u help me or not?

In that case, "not". Godd luck.

A few things i noted here. 1. If a professor asked you a question and then you went home to solve it, that would be a pretty good description of academic homework. Maybe you need to spend some time studying and discuss this question with your professor.

2.Claiming to be so specialized in a subcategory of electrical engineering that it is somehow beneath you to even understand maxwells laws and the corresponding rudimentary relationships is horrible, physics majors have to learn this stuff all the time and there is almost no chance they will be designing a standard power system or telecommunications system. Should they stop learning fundamental electromagnetism because they are specialized to it?

3. As you made it clear that this was a homework problem , even though you claim it is not specifically identified under the term homework, and this forum frowns on solving other peoples homework problems in college, you should expect no hel;p in solving it beyond some pointing in a direction to study.

dear RCE it was very amusing to read what u wrote down there and i am really appreciating your thoughts really...

first of all this question is not homework, it was directed to the guys who are supposed to be engineers and it was reasonable since the answer seems to be not a 10 page theory but just a delicate and gentle can be made as far as i feel even though i dont know the answer,

if it was a homework be sure that I wouldnt ask this since I dont admire the idea that students make the engineers here solve their homeworks, (many homeworks can be searched on internet but this question is somewhat tricky and cant find the answer still).

By the way I dont like the interference coming from others to the people trying to find a solution to their problems, if any question is disliked by moderators so they can check the content and let them or do not let them regarding their contents, I think it is not gentle to preach over the quality of the contents here, We all want to discuss the issues here ..
