For my antenna modeling code pymininec (which is a Python re-implementation of the original Mininec Basic-code) I was researching why the resonant frequency computed by Mininec is always a little too high (so the real resonant frequency is slightly lower…

This is an example of using the API of pymininec together with the API of plot-antenna.

This is a write-up that really should go into the documentation of PGAPack but I was unable to include plotly graphics into a github README.rst file, even using the proxy-site raw.githack.com (which is a page that serves html and javascript files with the…

This is an update on a previous post [Sch25] about a new implementation of non-dominated sorting for PGAPack.

Some of you know that I'm maintaining PGApack, a genetic algorithm package and a corresponding Python wrapper, PGApy.

In 2021 I set up a dynamic DNS server using the popular ISC bind DNS server and documented my configuration in a blog article [1].

[Update 2024-08-20: Correction of formula for L and equivalent radius] [Update 2024-09-19: Correction of citation of article by Stearns, Supplement to Antenna Book [5]] For my antenna modeling code pymininec (which is a re-implementation of the original M…

[Update 2025-12-04: Fix links in bibliography] I'm the author of an antenna plotting program called plot-antenna.

In my last post [1] I was wondering why my implementation of skin effect load in pymininec did not match the results we get from NEC-2.

I've recently implemented skin effect loading of wires in pymininec, my re-implementation of the Mininec antenna modeling code.
