Graphene resonator microwave cavity
Did you know?
A microwave cavity or radio frequency (RF) cavity is a special type of resonator, consisting of a closed (or largely closed) metal structure that confines electromagnetic fields in the microwave region of the spectrum. The structure is either hollow or filled with dielectric material. The microwaves bounce back and forth between the walls of the cavity. At the cavity's resonant frequencies they r… WebDec 1, 2024 · Further, the reduction of graphene oxide by microwaves depends on the oxidation degree of GO as pure GO exhibits very little microwave absorption and …
