This disclosure provides implementations of electromechanical systems (EMS) resonator structures, devices, apparatus, systems, and related processes. In one aspect, a device includes an evanescent-mode electromagnetic-wave cavity resonator. In some implementations, the cavity resonator includes a lower cavity portion and an upper cavity portion that together form a volume. The cavity resonator also includes an in-plane lithographically-defined resonator structure having a portion that is located at least partially within the volume to support one or more evanescent electromagnetic wave modes. In some implementations, an upper surface of the resonator structure is connected with the upper cavity portion while a lower mating surface is connected with the lower cavity portion. A distal surface of the resonator structure is separated or electrically insulated from the closest surface to it by a gap distance, a resonant electromagnetic wave mode of the cavity resonator being dependent at least partially upon the gap distance.
