HI ALL


I'm student, to practice E.M simulation I used D M Sullivan book (Electromagnetic Simulation Using The FDTD Method) how to calculate the SAR in 2D TM a plane wave source impinging on a dielectric cylinder by using fourier Transforms. Already I have from Sullivan's book the code in Matalab program, if I used the 3D code plane wave on a dielectric sphere in c++ is it possible to plot the the three electric fields by matlab.
I do appreciate any kind of help and personal contact through the following address

Hi Elgabo,

I think you have a principal problem: the SAR value is defined
as a 3d value! In 2d it does not make any sense, because you
have the mass=0 (no z-component)!!
For SAR calculation with a feed point exitation you have to use always
a 3d simulation program.
Maybe in some special cases with plane waves it is enough if you
simulate only one x-y-plane, because maybe in the z direction the field
distribution is the same over all the planes depending on your problem.

My understanding is that he is trying to calculate the TE or TM plane wave incident on infinitely long dielectric cylinder.

Hi elgabo
yes , it's possible to plot fields from simulation with c++. for that , you take the txt format for your program outputs (E & H) and in matlab load them

I hope it'll be helpful
