    Greetings.
    Quick question: I am trying to create a circuitthat is quite simple in theory yet to me a little uncertain in construction. Basically, I have a dipole-type strip circuit, or wire circuit if you will, theopposite ends of which I am aiming to be opposite charges. Basically, I amaiming to induce a positive charge in one end and a negative charge in theother end, such that these charged areas pulse in intensity under the influence of a microwave field (the inducer is a microwave energy field).


    My question is therefore what substances/structure/device do I use to induce a positive charge in one end anda negative charge in the other end, and of course what filter device do I usein the circuit to stop any charge discharging and to stop any polarity reversal (if a filter is at all required). The inducer I am using is a 1000W or so microwave field as per a standard microwave oven apparatus.

    The aim here is to create a bi-pole pulsing positive and negative point (opposite poles) apparatus. I amaiming to make the circuit about 10cm long (between the polarities) using as few items as possible, ideally just the wire between the poles, the +ve and –vepole constructs, and whatever else is needed to stop any discharge and pole reversal.

    Thank you for any help.

    The separation of positive and negative charge in a circuit is called potential difference or voltage. You can create a d-c voltage using a battery, a-c voltage with a rectifier, or something like a Van de Graff generator. A circuit that pulses under a microwave field sounds to me like a microwave antenna.

    Be careful what you put in your microwave. It probably came with warnings about placing metal objects inside.

    Microwave antenna is exactly what I am referring to, but this one I am trying to construct is a little different. The trick of construction here is to ensure that the different polarities remain exclusively positively and negatively charged, while of course pulsing under the effect of the microwave field. Thank you for the warning about the use of microwaves, as I also would caution anyone placing foreign objects other than food items in the microwave. The purpose of my question here is to put down in paper the logistics of creating pulsing charges using a microwave antenna set-up that has exclusive positive and electric poles under the influence of a microwave field. For instance, would I need to construct the ends of the circuit with special materials to encourage a positive charge in one end and a negative charge in the other, and what type of gate would I use between them to ensure that there is no discharge between the polarities. Thank you again for any help.

    Your signature is wrong, Harold is just too nice to tell you that your understanding of electronics is sadly lacking. Before you can invent something, or build a prototype, you ought to have a thorough understanding of the subbject. All to many on these forums seem to have a knowledge based only on what we call 'hollywood physics'.

    Apologies. When I ask a question I am actually asking a question. I am not trying to be smart about it. I "am" seeking an answer. No theory to prove on this one mate. Any help from you if that's possible would be much appreciated.

    (apologies for the double post)

    It is actually a hard construction. The design is aimed to be the solution to a problem in a book recently published about the effect of rapidly raising and lowering the charge of a structure under the influence of microwaves while preserving the integrity of the chrage (not having the charge short out). I've done a bit of reading behind the question already you see.

    Moreover though, Harold answered the question really well, implicating that a DC battery is best used to keep the circuit tame. Thanks Harold. That would seem to be the simplest and and perhaps best solution.
