our project is numerical analysis of CTS antenna array for which we have to write code using fdtd method.we refered the circular wave guide codes in your forum,can u give us any suggestion regarding codes.

It should be easy to use openEMS to solve such a structure.
Read the tutorials at http://openems.de/index.php/Tutorials and look at the provided examples in the source code archive.
The provided examples to start with are Coax_CylinderCoords.m and Coax_Cylindrical_MG.m
Both model a coaxial cable. Use the methods described in http://openems.de/index.php/Tutorial:_C ... rn_Antenna to add a antenna pattern calculation to your model.

But if you have to write the fdtd code, then have a look at our source code. Be careful: obey the GPL license and give proper credit.

Thanks a lot 4 ur suggestions I have some queries ??

1. I have downloaded directly openEMS from our website , is there any other software i need to install ?
2. What is the use of AppCSXCAD , Paraview ....?
3. Do openEMS accept the structure of my design ,then generate radiation patterns, S11,..... or to write the code ???
4. How FDTD method is applied to any structure in openEMS ????


Many queries arising because i hope it wil benefit our team .....

thanks a lot ... i have some few Queries???

1. What are the software i need to install for openEMS???
2. What is the use of appCSXCAD ?? will it output the radiation pattern or used for designing the structure?
3. Will openEMS generate codes or we want to write ???
4. How fdtd method is utilised n t openEMS ??


our team hopes tat openEMS will help to do our project ...

Take some time and read http://openems.de/index.php/OpenEMS#Installation.
Then read http://openems.de/index.php/Tutorial:_First_Steps.
This should answer questions 1 and 2.
For question 3 see http://openems.de/index.php/Tutorials. You need to write Matlab (or Octave) code to describe the geometry and solver settings.
For question 4, download the source code and have a look. It's an open source project, so you have the oppertunity to have a detailed look how this all works.
