I have large microwave resonant cavity used for our experiments; as part of our experiments we would like to add plastic inserts in the cavity. Unloaded, our cavity has a Q factor of >10,000 at its f0 of 340 MHz, but this goes down to about 2000 or lower when I insert my plastic. I understand that I can't expect to put material inside the cavity and still have a Q factor so high, but I feel like I should be making more of a conscience decision of my materials.
Does anyone know of plastics typically used to be "transparent" in in the sub GHz frequency regime? I imagine this application has occurred before with anechoic chambers or other measurement cavities, but I haven't been able to dig up anything helpful yet.
