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
I want to build a low-cost polarimeter to study circular dichroism (chirality). What type of samples can I use? I am looking for samples that can be found outside the laboratory.
