Xilinx has IP cores that can do that for you. If you have Xilinx ISE, open the core generator and choose one of the Logicore IP Fast Fourier Transform cores. The doc is here https://www.xilinx.com/support/documentation/ip_documentation/xfft_ds260.pdf
You can set the impedance using a discrete port (take S-parameter port, you can then set the impedance directly). But it will become inaccurate if the guide is a few wavelengths or larger.
With the waveguide port you'll get the impedance defined by the geometry of the guide and the mode you...
Say I want to search for "Blah" in files with a txt extension. I'd do something like this:
IFS=$(echo -en "\n\b")
for x in $(find . -name "*.txt")
do
grep "Blah" "$x"
done
You can also concatenate it in one line by replacing carriage returns by ;
In principle yes, it all depends on the way you look at it.
You can represent an right hand or left hand circularly polarized wave by a superposition of two orthogonal linear states with some phase shift.
Conversely you can represent a linear wave as a superposition of RHCP and LHCP states. It's...
HFSS relies on IronPython (see ironpython.net).
.pyc files are generated by the reference python interpreter (cpython) and are not recognized by IronPython.
The latest versions of IronPython include a script called pyc.py which allows to generate executables, but I've never tested it so I can't...
