Hi, Jain.
I don't understand your question, do you want add Ferrite to library of CST as material?
With my best regards
Thanks Mr. Abdulrahman,
I have defined Ferrite but Have little query about the freq. during the ferrite definition. What value should I put my desired freq band, or Centre freq, or Freq at which Ferrite data measured of any other????
Ferrite is a high frequency suppressor but as far as modelling is concern, its electrical effect is a equivalent to paralle combination of RLC. For preciseness, RLC combination with series of other RLC and another series component R makes an equivalent circuit. Values of reactive components L and C are of the order of micro henry and picofarad respectively
Hello, i am trying to define Ferrite as a new Material in CST as well. Specially the dependency of complex permeability and frequency is important for me. I have datas about this dependecy as a .txt or .xml file. How can i set up these datas as a new material in CST?
For designing an isolator you must use an anisotropic ferrite, which is called gyrotropic in CST. The ferrite must be biased by a static magnetic field in the correct orientation. You must get the dielectric and magnetic properties for the ferrite from the manufacturer.
You enter th dielectric properties via the material parameter through the column on the LHS under general and conductivity. Then the gyrotropic properties under dispersion, You draw down from the arrow to get gyrotropic..You enter all the data of your ferrite to the list.
CST will plot all dielectric and magnetic properties on a chart..
All you do next is to simulate your isolator. Please enjoy!
Dear S. Asghari
in any case in simulators like CST or COMSOL, to definition of a material you just need to define the dispersion diagram or dispersion equation for the specific material that you want to simulate. So, you need to find a way to write dispersion equation based on zitta, permitivity and permibility which leads to use maxwell's equation in basic forms and govern the dispersion equation based on the parameters of the material.
