You'll forgive me if I'm not in a mood to be generous. You might consider adding some ordinates to your phase plots. Here's the definition of "ordinate": "The y-coordinate on an (x,y) graph" I'm not sure what you are asking for. The graphs were generated by Excel. What exactly are you saying? Do you want me to add the dots for the data points? Also, some credit to Roy for making all of the calculations for you might be appropriate as well. (You might ask him how he does it.) How he interfaces to NEC? I'm not sure what you are asking for. EZNEC is a great piece of software but the calculating engine is NEC. I doubt that even Roy knows the NEC equations. We still haven't seen any of your work. By work I mean calculations, not typing i.e. assumptions, deductions, inferences, and proclamations. Assuming there are actual values, it would be good to know, for example, what calculations were made in order to arrive at the phase angles in the plots. I don't know what "work" you are asking for. All I did was run EZNEC simulations and report the results. The phase angles are calculated and reported by the NEC calculating engine. I don't know what equations they use, but probably the method of moments equations. I believe Balanis has a chapter on MOM equations. The only equations you provide are for instantaneous amplitude as a function of phase angle for a standing wave. Obviously that isn't suffiencient for obtaining the data in your plots. It's very poorly done. D+ All the data is directly from EZNEC, Jim. Download coil505.EZ and run it yourself. It is NEC that is doing the calculations. The data reported by EZNEC was entered into coil505.xls and Excel produced the graphs. Your objections seem really strange and petty. -- 73, Cecil, w5dxp.com |
