In our design, the three-layer MM can form two isolated Fabry-Perot-like resonant cavities: the first Fabry-Perot-like resonant cavity constituted the layer M1 and M2, the second Fabry-Perot-like resonant cavity constituted the layer M2 and M3.
The resonant cavity is represented by a resonant LC circuit with a resonant angular velocity ([omega] = (1/[square root of LC])).
To validate our predesigning procedure, HFSS simulations were run, and excellent agreement with our results confirms the effectiveness of the equivalent resonant cavity model for thin hybrid antennas.
In conclusion, the ZnO microrods with hexagonal cross-section were fabricated by vapor-phase transport process, and an individual microrod was employed to construct a resonant cavity. Under the excitation of the 1200 nm nanosecond pulse laser, the three-photon excited UV laser was obtained.
We believe that these two elements working in tandem may offer a superior and more sensitive scheme for detecting resonant signals within the cavity, such as arising from the detection of Skivie axions (or any other particles which could be produced from an Inverse Primakoff Effect in a resonant cavity).
To increase Q further, a superconducting resonant cavity has been proposed for second-generation EmDrives.
The new study, though, shows otherwise. It details experiments carried out by NASA's Eagleworks Laboratories and describes a radio frequency resonant cavity thruster - EmDrive by another name - that is capable of producing thrust of up to 1.2 millinewtons per kilowatt in vacuum.
The setup is a radio-frequency resonant cavity shaped like a truncated cone, with one round end then larger than the other.
According to Wired UK, the study found that test results indicated that the RF [radio frequency] resonant cavity thruster design, which was unique as an electric propulsion device, was producing a force that was not attributable to any classical electromagnetic phenomenon and, therefore, was potentially demonstrating an interaction with the quantum vacuum virtual plasma, Discovery News reported.
[3] The Schumann Resonance signal is generated by tropical thunderstorms and is a set of resonant modes within the resonant cavity formed between the earth's surface and the D-region of the ionosphere.
