Hi does the quantum mechanic play a role in the intrinsic nature of electromagnetic fields and its propagation? massi

It seems that soon I can chose or CST or comsol software but I should still learn how to do it..

yes it is that

I am in the last year, I have some experience with cavity and antenna radiation but I am not such expert, I didn't know this book thank you m

I just need to solve this exercise to calculate the system behaviaur, please if you have a book about it or suggestions I really appreciate. thanks in advance cheers massi

it is a simulation exercise, cheers massi

the system looks like this massi

Hi , what happen if a half dipole linear antenna is placed inside an electric conducting resonant cavity? The cavity itself is the conductive ground of the half dipole antenna. How can I solve such problem in which the cavity works as resonant cavity and it is part of the antenna itself? Cheers...

thank you massi

thanks for reply, so the source itself perturbates the wave impedance; I did this question because I found on the web this picture that I show you in attachment (the reference is given in the file). I did a bit confusion in the previous message I sent, Actually it refers to electric field source...

Hi All, what is the reason why very close to an electromagnetic source (Fresnel Region), the wave impedance Z0 in free space for electric field and magnetic field is not the same? Z0 for magnetic field increases and for electric field decreases by increasing the distance from the source...

ok I see, thank you! massi

Thank you!

thank you very much, this forum is wonderfull ! m

Hi the difference between a loop antenna and a magnetic probe (B-Probe) is only that the loop antenna works in far field and B-Probe works in near field? The standard features of magnetic antenna (antenna factor, impedance matching, radiation patterns, efficiency, ecc) have the same definition...
