hello! I have need of a circuit capable of generating a rapidly oscillating, strong electric field between two electrodes (or a single electrode). Ideally, several kV would alternate between two electrodes at up to 10 MHz frequencies. I suppose what I'm asking for is basically a capacitor capable of switching its charges. I've played around with a few of my own circuit designs. I've been avoiding the LC in series because it simply wont oscillate as fast as I'd like it to with the voltages involved. They mostly involved a function generator, mosfets, and DC power sources. However I am not an expert, and there is a good chance none of my designs will work. I understand I could just place the electrodes very, very close to each other and even a tiny capacitance would create a "strong" electric field, but for my purposes the electrodes MUST be at least an inch apart. so two things are required: 1. 10~ MHz frequency 2. kV's between electrodes up to 1 inch apart Does this kind of device exist? and if it doesnt, is this kind of device even possible?
