Hi venkatramesh69,
GSM 900 is based on ETSI standards; you will find all documents free on ETSI homepage
e.g. https://www.etsi.org/deliver/etsi_gts/05/0505/05.00.00_60/gsmts_0505v050000p.pdf
To your question: power transmitted... see page 11
Hope this helps:

Hi aliman8,
- take a look here: **broken link removed**
It is old stuff, but for a first start it is not so bad, I think.
And it is completely freeware!! :-)
Wish you a nice start with FDTD!!

Hi ammadhumayun,
I personally can recommend 'Filezilla Server'; ist is easy to configure, and it's open source:
FileZilla - Server Download
hope it helps: Ricy
Hi jayaprakash2020,
can you explain in more detail what you mean with "cancer detection"?
If you want to start with FDTD a very nice book is from D.M. Sullivan: 'Electromagnetic Simulation using the FDTD Method', 2000. Inside the book you find some very simple Matlab Code for 2d calculations...
Hi alpha82
- I think with every FDTD program you can do it!
e.g. freeware (under Linux): LC Cray **broken link removed**
If you like it more comfortable e.g. Semcad light (for 99USD):

But also with other FDTD programs of...
Re: 3D modelling
Hi,
for 3d modelling I use Blender: https://www.blender.org/features-gallery/features/
It works great!! ...and it's freeware.
Hope it helps for your problem! :-)

rf amplifiers mixers simulation tool
Our company uses Semcad (www.semcad.com). Maybe its on interrest for you?
It's also possible to import CAD files from print layouts (Gerber) and circuits from SPICE.

Re: 3d fdtd model files
hi,
what kind of data format? you can find a lot of free models
here (don't know what you search): http://www.3dcafe.com/

Hi Gouzou
you have not described what you like exactly do with your simulation? If you like to do dosimetry you can forget any implicit method like finite elements (HFSS) or similar. You have to use an explicit method like FDTD (finite difference in time domain e.g. Semcad...
Hi Kender
of course: the dielectric properties of human tissue are depending on the frequency!
Take a look here: **broken link removed**
You can type in your frequency (13.5 MHz?) and get the values for different types of human tissue; e.g. skin dry: sigma=0.237/eps=286.3
hope this helps :-)...
Re: About RF simulators
Hi tjunqueira,
you wrote, that you have to simulate a wave combiner in 3D: I think it is better if you use a expilicite method (e.g. FDTD or FITD; -you simulate explicite in the time domain) as an implicite method like HFSS (FEM,... you have to invert the whole system...
Hi DACADC
if you need (only) static fields in 2D, I think a good alternative is the
Matlab PDE toolbox; it is based on finite elements:
https://www.mathworks.com/products/pde/
You can easy download a 15 days trial version there. Hope this helps :-)

manual femlab
which version? between the earlier v2.3 and 3.xx are big differences...
a good tip is to order from comsol the conference proceeding cd (it's for free).
