In combination with farfield monitors, the radar cross section (RCS) of a scatterer may be calculated. The plane wave excitation source provides you the opportunity to simulate an incident wave from a source located a large distance from the observed object. ContentsįSM export as NFS nearfield scan data exchange format

Nearfield sources allow for the excitation of the time domain solver, the integral equation solver and the asymptotic solver by nearfield data described in various formats.

Farfield sources allow for the excitation of the integral equation solver and the asymptotic solver by data exported in a farfield source file by CST Microwave Studio. If you feel like deleting, something like: delete results.txt might work in the script, or for matlab memory stuff something like: clear all.Field Source Overview Field Source Overview Several types of field sources are available for imprint in CST Microwave Studio: Plane wave sources allow for the efficient excitation of linear, circular or elliptical plane waves at the boundary of the calculation domain. You don't need to delete anything, the old results are automatically overwritten. Don't worry it is very easy, it is just a copy-paste thing.įor your third question. This is the command that turns the CST Macros into Matlab code. For instance open CSTExportFarfieldsourceAngleStep.m and get oriented with the matlab invoke command that I use. Open one of my m-files (besides an example file).

That Macro is the solution to your problem! You need to turn that Macro into matlab code and you are done. You can see that code by going to Modeling->History List->Edit.

That way, CST will generate a history archive containing the vba script of the thing you just designed.

Go to that CST design and design whatever you were trying to script in matlab and got the error, manually.

That way you will isolate the error (You obviously done that) and you will also have the corresponding CST design that is one step before that error.

Run your matlab script and comment every line of code right before the point that you get the error.

The best solution for all of these when you are trying to create a new functionality for the code is: Besides that, there is also a general strategy to follow when you are trying to add new functionalities that works every time and applies to your second question too. Yes, one of the many reasons might be that the name of the farfield in your CST result tree changes when it's combined compared to the single element farfield, therefore you need to edit inside the CSTExportFarfieldSourceAngleStep.m the name of the farfield that you need to export. At first you did it with one element and it worked but then you combined them and it didn't.

I think what you are asking is how to export the combined farfield for your array. Ok it took me a while to understand what you want in the first question. But I'm facing some problems please help me with the commands.įarfield (f=33.5) +2+3+4,].txt Thank you for your code, it really gave me an insight into how to control CST from MATLAB. (File name Excitation List and Selecting_phases)ģ.If I want to rerun the simulation, how to delete the old results automatically and rerun? If I want to excite the antenna array patches with different phases by selecting the source type as 'Selection' and changing them after selecting 'Excitation List' what commands Do I need to use, I tried but I'm getting an error as a command not recognized.I tried to amend your code but I'm getting a weird error, I have attached the screenshot of the error as well ) (I have attached a sample file, i'm expecting to export the far-field results in the same format, the file name is 'farfield (f=33.5) +2+3+4,].txt') At first, I tried to export the far-field, initially, the code was working fine and exporting the far field as the source for all the values of theta ranging from 0 to 180 and phi ranging from 0-360, but how can I export the normal far field for all the values of theta ranging from 0 to 180 and phi ranging from 0-360.I ran your code on the antenna array I have designed by doing some basic modifications to the code.
