My dictionary says: "Gauss`s theorem----The summation of the normal component of the electric displacement over any closed surface is equal to the electric charge within the surface." James Clerk Maxwell studied the work of others such as Ampere and Gauss to develop his equations defining the relationships between fields, charges, and currents. Maxwell found that dislacement current should produce radiation the same as conduction current. So he made a correction to Ampere`s Circuital Law. Art is right. Discovery is a continuous process. Maxwell`s equations have now been adjusted for curved space and time. But, I`ve searched in vain for "gaussian antennas". If Art has an invention, maybe he will explain. Best regards, Richard Harrison, KB5WZI O.K. you haven't been around for a while so I will give you the benefit of the doubt in that you are not aware of my new series of antennas that gives the yagi a run for its money and infact meets the needs of a lot of industries. Many have asked for a mathematical aproach accepting no other well that is their problem. I am going back to first principles which most of the masters did without forsaking equilibrium and the mathematical conformity that must be kept. So if you have an open mind, pen and paper I will start. Anybody who is aware of Gauss can think back to the enclosed ballon or what have you where there is a pill box at one end. Hopefully you have drawn that. Now on the pill box you should be able to draw say three static images Hopefully you have done that O.K. Now some of those who are not familiar with things will get lost at this time. For the educated you can now modify the static field that you have drawn and expand it by making it a Conservative field where theoretical vectors are added to each static partical bearing very much in mind that all vectors are theoretical and all have "zero" length. O.K. take a moment and look at what you have drawn which is a rfield of projected static particles with theoretical vectors on them and nothing to show inside the enclosed arbitary border from whence they came ie we did not show where the static particles came from. Now when you applied vectors to the static particles you added two each at right angles to each other, Why? Because for the vectors to represent a radiating array in any form it must be in all three cartesian directions. At this time we will project from each static particles a dotted line to the end of a element length such that a cluster of elements now show where the static particals came from. Hopefully you are still with me. Gaussian law is o.k. as far as it goes but when deevising antenna arrays we need something more i.e the addition of time. So we pull out the written version of gausses static law and enlarge it to account for a time additive. And we can do this by adding the metric of a space in time to the original statement bearing in mind that to do so equilibrium must be maintained. Dinner is here will resume in half an hour. Take time to think about what I have discussed so far but without pre descisions so that you can follow the flow better later. Art |
