For the past 5~6 years, I have been using Eclipse (plus Pydev) for Python scripting. It is a great IDE, not only for Python, but for many other programing languages such as Java, C, C++, Fortran, etc. However, Eclipse is quite a resource hungry program. Then, I found a lightweight…

Feed Polarization: When any of the “conic” reflectors are used, it is of interest to specify an “ideal” polarization of the incident field such that the currents induced in the reflector flow in parallel paths. This specification will permit the reflector to be formed by parallel conducting wires or slats…

I couldn’t find a simple script to plot Zolotarev polynomials. So, I wrote a python script to do the job. You can download the python script here: https://github.com/zinka/arraytool/blob/master/arraytool/src/arraytool/Zolotarev.py…
