Dave "It" is called "courage of his convictions" something you cant buy. Do you still say you cant add the variant of time to Gauss's law?. Derek. Gauss's law is a law of 'electrostatics' as art so frequently states. STATICS is static, ie NO current which would be implied by adding a time component to the charge or field predicted by Gauss's law. If you have a time variable charge you have a current, if you have a current then you have to include the magnetic fields, and the curl of the electric field, and hence end up needing all 4 of Maxwell's equations to define the complete solution. So yes, i say you can not add time variations to Gauss's law as it stands alone and completely describe the solution to the fields produced. i.e. simple proof. define any shape surface with no charge enclosed in it. by Gauss's law the net field through that surface must be zero. you can have charges sitting just outside of it, lets say a single electron is just outside of one side of the surface. if you integrate the field from that one electron it goes in one side of the surface and out the other and all still adds up to zero net field as require by Gauss's law. now for the hard part.... move the charge a little bit closer to the surface without going through it. we must all agree that while you are moving it the electric field strength through the surface closest to the charge is increasing, so in order for the total flux through the surface to remain zero the flux moving out on the other side must also increase. BUT because of the effects of the other 3 Maxwell equations that limit the speed of propagation of that field to c it can't happen instantaneously. so for some period of time the net flux through the surface is not zero as would be require by Gauss alone. reductio ad absurdum, QED, take your new theory and.... hmmmm, 24 hours and no rebuttal? come on, some of you art suckups that i haven't plonked yet must surely have a logical reason why this isn't correct? maybe the new non-newtonian static electrons get magically pushed through the integration surface and make up for the extra field? oh wait, then they wouldn't be static any more would they? and where it the diamagnetic surface that they levitate from?? oh well, back to the 10m contest, thats even more fun than pinging this group. Should be easy enough to check the claims. If as Art suggests there is a constant interchange of particles in the surface element of a radiator, then some detectable physical changes should take place. Construct an antenna using anodised aluminium (aluminum for US readers) for the radiating element. Take some smaller (non resonant pieces) and mount them some distance away from the antenna but exposed to similar environmental conditions. Leave for a year or so and then examine the radiating element surface and compare with the samples. Is there any difference in the surface structure? The samples should be non resonant, of the same batch material as the antenna and arranged so that they are not likely to radiate or absorb RF energy from the test antenna, while still being exposed to the same weathering and other factors as the test antenna. Mike G0ULI Using anodised al- Hide quoted text - - Show quoted text - Mike that is a novel aproach but it does appear that exposure to the antmosphere of any element cnnot be prevented i.e. pin hole propargation which is evidenced by my mercedes plating processes. However the guts of GUT is the unification of mechanical laws ( revolving around equilibrium) with electro magnetic laws. There is no simpler way to verify that cvonnection than to verify the required angle for a radiator to produced a uniform radiation such as horizontal polarization. This is a direct connection that can now be resolved by the use of computor programs that follow Maxwell and not the equilibrium dictates of the mechanical world. That is the test for finality in this quest, an acceptable unity between the sciences.I am beginning to believe that most of the participants do nor have a computor program or even a trust in the results when it shown that is formed around empirical evalution and not solely on Maxwells laws without suspect additional conditions.To my mind anybody who is antenna computor savvy would leap at the chance of determining the structure of a particular radiator to become a leader in this debate, but unfortunately there are none. When the programmer involved with Eznec refutes the validity of accepted mechanical laws or dismisses the notion of non frictional environments there would appear to be some merit in questioning their "corrective" actions which for a viable law such as Maxwell's is somewhat fraudulent. For the same person to descend into personal attacks in defence of his posture certainly suggests that his limits of viability. have been some what strained Like Cecil he has a large amount of knoweledge which in itself is not enough when the quest in total victory and elimination to all oponents What a waste of such valuable brain power. Art Unwin KB9MZ.....xg (uk) has been some what strained Hi Art, Provided that the antenna and sample pieces are exposed to the same atmospheric effects, gross damage such as random pinholing to the surface will be identical in all pieces. However I believe that the antenna element should additionally show a regular pattern of disturbance caused by standing waves which might be identified using electron microscopy or just possibly a high power visual microscope. Computer modelling has its place, but all computer models are constrained by the constants and formulae used to calculate the final results. When the computer model does not agree with physical measurements in the real world, then one of three conclusions may be drawn. The wrong data has been entered, the real world measurement is in error, or a previously unknown variable needs to be taken into account and added to the computer model. Of the three possibilities, the last is the most unlikely if the model is mature and correctly predicts the behaviour of known, experimentally proven systems. In order to successfuly add a new calculating method to a computer model, it must correctly match the existing results while also correctly predicting the new previously unknown behaviour. This is not a trivial task and it is insufficient to just add a correction factor as this just demonstrates that the true nature of the problem is not understood. NEC based programs follow well proven principles, but are not the holy grail in being able to predict the performance of all antenna types or configurations. They can accurately predict 'established' antenna design performance in most circumstances and give a useful insight into what properties a new and previously untried design might have. The programs are, of necessity, constrained by the accuracy of the physical measurements and formulae used in writing the original program. I do not consider the challenge to Newton's Laws to be valid. Just because there is no true vacuum anywhere in the universe, as far as can be established, then all objects will eventually come to rest due to friction. This does not invalidate the premis that in the absence of friction or any other external influence, an object would continue in motion along a straight path forever. Ultimately whatever predictions are made by computer modelling programs or theory, the only measure of success is by physical measurement in the real world. Mike G0ULI |
