and also i should include G (gain) in the equation so it all don't come out symetric but i got no idea how should i do it...

Homework Statement I need to plot an electric field in some range around base station, for example in range of 200m. EIRP=57,5dBm G=1 for the first example N=4 Homework Equations E=[2*sqrt(30*N*P*G)]/r P=10exp[(EIRP-30)/10] EIRP=57,5dBm G=1 for the first example N=4 The...

finally...it's ok...stupid mistake...now it is as it should be :)

Yes, thank you very much...it's something like thaht, but I don't get why the values for H are so much bigger than expected...for example in 0 I'm sure that H needs to be 0,5 and on this graf it is 10 times bigger...the funcion looks allright, but this results are confusing...

Just one correction K=1/E is not correct, it should be K=(1/E)*(pi/2)^2

Hey all. I have a little problem in Matlab. I attached word file in this post where the problem is explained because I can't write those formulas here. It's not hard, just need to put few formulas together. I also wrote what i tried, but the result is not good. I calculated it manually and...

thanks a lot...this was very helpfull! :D

well i rewrited this code from the book in which there is an figure of solution due to this code...i also found similar code on the net and again the same problem...i'm not good in MATLAB but i assume that magvector should be some function and that i don't have to define it but MATLAB doesn't...

% varibles % I current(A) in +phi direction on ring % a ring radius (m) % Ndeg number of increments for phi % f angle of phi in radians % df differential change in phi % dL differential length vector on the ring % dLmag magnitude of dL...

thanks very much

Hi, I red that in Franklin's book "Classical Electromagnetism" there's off-axis magnetic field of a solenoid solution...well I need that but can't get the book... so I'm wondering if anyone has that solution for magnetic field of a solenoid analytically? It's important and I would be...

nothing at all?

hello, i'm wondering is there any review of most used methods in magnetostatics? and also if there are analitical solutions of distibution of magnetic field in cylindricall coordinates for: current loop, solenoid, current flown cylinder, coaxial cable and magnetic buffer (protection)...
