Asymmetrical Capacitor Thrusters have been proposed as a source of propulsion. For over eighty years it has been known that a thrust results when a high voltage is placed across an asymmetrical capacitor, when that voltage causes a leakage current to flow. However, there is surprisingly little experimental or theoretical data explaining this ...

Abstract: This brief presents a dual-band antenna decoupling technique with independent control using composite capacitors. Due to the inherent frequency-selective characteristic of the decoupling structure, the decoupling in one band has almost no effect on that in the other band, so the decoupling in the two bands can be independently controlled simply by …
