lyd1ng / hf_waveguide_simulation

What is the hf_waveguide_simulation?

The hf_waveguide_simulation mostly consists of two python scripts
to simulate the radio frequency field of h-modes inside a rectangular
waveguide.

waveguide.py

The waveguide.py script can be used to calculate the vectors of
the electrical, magnetical or the pointing field of one h-mode
inside a subrange of the waveguide.
By specifying a start and a stop time the changes of the radio frequency field
can be visualised.
The output is compatible with gnuplot and gnuplot animated gif exportation.
