FRACTAL GENERATORS FOR EM PURPOSES

Maybe you know so-called L-Systems, or "turtle graphic".
There exists many papers on net, just search for "L system" to understand.
I've found one program for Matlab and realized that it's very valuable for all ppl interested
in fractal antenna research!!
I've added a piece of lame code which creates .3dt file for IE3D so you can make fractal wires
and polygons easily (this example is peano_export.m). You need to manually add POLY, WIRE or TRACE
at the start of generated file. This file can be also used for creating curves in MWS
In attachment you will find generators for various seeds and transformations...
ENJOY!!

nice!

here's a mma pkg that maybe you know of. try these for example :

<<Fractal.m
KochSnowflake[4]
Hilbert[4]
HFractal[4]
Sierpinski[4]

Another feature of IE3D you may enjoy is the User Defined Object on the IE3D 10.0. It is on the IE3DLibrary. The User Defined Object allows you to program your shape in the computer language you know. You can program any complicated shape including fractal antennas. If you program your User Defined Object based upon variables, you can even allow IE3DLibrary to optimize your complicated structures.

Thank you for suggestion, Jian, I will check this feature (unknown for me until now)
BTW - some notes on IE3D which troubles me a bit now...

- I miss a simple way to parametrize the structure in MGRID and then possibility to simple modify objects
- also high-level undo might be useful (or even accompanied with history list)

I'm very pleasured by implementation features above in CST-MWS where post-editation or assigning label names for structure parts is so easy...

I think there can be more suggestions to improve IE3D from other users here?!
Maybe we can make particular thread to discuss it more...

Cheers,

Yes. We will try to imporve it. The IE3DLibrary is the 2nd interface for IE3D. It is a parameterized interface which you suggest. The IE3DLibrary 10.0 is not very stable yet. However, the IE3DLibrary 10.1 will be very stable. It has a bunch of parameterized objects and a user is allowed to create his own object using any program language. We are thinking to build label names into MGRID and MODUA too. We may eventually keep the history a project. This should not be difficult after the release of IE3D 10.1. The IE3D 10.1 is using XML format. We can certainly put a project into the hierachy of an XML file so that the user will be able to access the history easily. We will try to do it on the IE3D 11. Any more suggestion, please feel free to let me know. Thanks!
