Your theory used in Eznec was designed around known "reality" because you found the need to add the proviso that there was a sino soidal current at all points on the radiator. Number one, it is not legitamate to add a proviso or a special condition to a known law.( Electrical or Mechanical) Number two It becomes a worse problem when the proviso added is in error. Number three, You should not retain a proviso if it proves incorrect . The fact that present theory has passed the test of time means nothing. The threat of retaliation trumps science when humans are concerned. Gallilao never saw the day that the earth was proven round which stood the test for a very very long time. But you could explain to the world how a sino soidal current passes thru a distributed capacitance and still retain its properties as it encounters every segment. This is per the proviso you have placed with existing Maxwell's laws with respect to your computor program. But no you can't! Until then I don't think you are equipped to say that written theory can be taken as fact.Especially when known laws are twisted so you can gyrate your program to known reality. The old saying still stands, Garbage in will produce garbage out unless the outputs are subject to reprocessing ! Art Unwin...KB9MZ snip Art, I'm sure Roy is quite capable of defending himself against your accusations, but I think you are being a trifle unfair. EZNEC is a simulation designed to predict the performance of an antenna design. Being a simulation, certain assumptions and approximations have to be made in order for it to work. The fact is that in most situations it does provide an accurate prediction of antenna performance. There are some special circumstances where it won't. Integral calculus has been described as one of the greatest advances in mathematical science, but that is still only an approximation method and nobody complains about that. Let's all behave and not argue okay? Best wishes Mike G0ULI- Hide quoted text - - Show quoted text - But I am behaving. I am sure that both Roy and others who deal with NEC4 will admit that they have played with the truth with respect to antenna programs. I would venture to say that computor programs are good at what they do but it is for all the wrong reasons. Maxwell's laws are just that..Laws. It is mathematically fraudulent to add anything to those laws under the banner of Maxwell. When Roy left the ARRL circle he challenged antena companies to verify their claims with respect to gain. By the same token I am challenging to prove the veracity of the additional statement that a sino soidal current is present at every segment point. Not is it only mathematically illegal to modify a law the addition also defies all electrical laws. A radiator has distributed capacitance and I am not aware that a capacitor will allow the passage of a time varying current, this is what the programing states. He ofcourse can justify why he did this to the satisfaction of all but he cannot justify the insertion of such. Now my antenna operates quite nicely following another aproachyet Roy vehamently derides this new aproach when he himself cannot verify his own actions. Fairness can be seen in different ways. He can be belligerent in analysing my aproach yet at the same time defend an action that he cannot prove to be true. A person always has the right to defend himself especially against those who are mentally challenged. When he provides how distributed capacitance does not affect the time varient that Maxwell states is a titular point of his laws I will readily retract that remark. Until that time I will defend the veracity of my aproach which succesfully produces antennas and arrays in a smaller volume that present theory predicts as impossible. As an adder, I am discussing antennas and not "systems" as Roy would imply. Nothing personal, Like Reagan I like verification since trust does not prove to be enough and I will always defend if I am attacked. Best regards Cheers with a Black and Tan Art Unwin.....KB9MZ...xg |
