What is the ionization efficiency of hydrogen as a function of frequency and pressure?

18 September 2019 0 3K Report

I should need an absorption percentage plot for a theoretical antenna efficiency of 100%

From 10-13Mhz it should be used a helicon antenna, but there are high-efficiency RF generators at 470Mhz and 2.4Ghz that could be used instead
