Water, specifically, stops mm wave signals. While it can't get through a wet piece of paper, it will go through a dry one just fine.

- taneq 7y agoPresumably the key property is conductivity, rather than water specifically? I'd expect a sheet of tinfoil to stop mm waves as well as wet paper.
- Sharlin 7y agoProbably it is about the fact that water is polar and readily absorbs microwaves. Which, of course, is how microwave ovens work. (The standard 2.4 GHz frequency is actually not absorbed as well as higher freqs; this is a deliberate choice to let the radiation penetrate deeper into the food and heat it more evenly.)
- maeln 7y agoDoes this mean that we can expect a bad FR2 experience during rainy day ?
- cbruns 7y agoYes.
