RF Emission

how and when? you turn it on.

nice

Let's say that we only put 360 degrees of signal into the feedpoint. How does that cause emission, and when does the emission occur?

Does the antenna emit for 360 degrees? Continuously emit? Or emit for 180 degrees, and then emit the other 180 degrees directly after the first 180? Each element changes polarity after 180.

So each element is actually emitting at twice the frequency? It would emit one polarity then stop for an instant during crossover, then emit the other polarity?

“Only” 360 degrees? Can you define differently if you’re thinking more please.

Your second statement/question is understandable/accurate, so you’re on the right track

Research standing waves, and harmonics too. Understanding the proper wavelength for antenna lengths. Dipoles are a great jump off point for that.

This may be less intimidating than my first link:

I have asked that question for over 50 years. I have yet to hear or read a clear, precise explanation of how and when the emission occurs.
Is it that difficult to describe.....or to understand?
Do we all agree that each element must emit twice for every input cycle?

No. Why would it not emit continuously? Why would you keep asking a question that could not be answered to your specifications for 50 years? The universe does what it was designed to do, not what you think it should do.

When we receive an emission, do we not detect a zero emission every 180 degrees? When the polarity changes?

A node, if you will.

...."Dipole antenna electric field generation. ... When a signal is fed to this antenna, it should induce an electron flow. However, it is also said that this electron flow produces high concentrations of electrons on either sides of the dipole alternatively during transmission.Jan 22, 2017"...

..."The signal generator produces a frequency whose wavelength (λλ) is twice the length of the antenna (a half wave dipole). This is optimal for a dipole to achieve best conversion of electrical power to electromagnetic radiated power."...

The current is high when the voltage is low and vice-versa (see SE's post). Not all quantum effects are known. Emission is instantaneous when the signal is applied as far as anyone knows.

I do not think that it works that way. I believe that 180 input on one element, and 180 input from the other element, builds a 360 spherical field around the dipole. It only takes 180 input for this and the radius of that field is 1/2 wavelength out from antenna. At the end of that 180....the field dis-associates from the charge(current) in an instant manner. The field velocity of that field, changes direction in a snap. The emission is instant. The field direction changes from angular(field) to linear wave. All the radii from that field now fly out in a linear direction. A radius length wave flies in one direction and the other half wave flies in the opposite direction. The wave has a 180 duration or length. When the wave is adsorbed, that takes 180 duration.......and the absorber REACTS with a 180 of bounce or reaction, giving a full 360 response, with only 180 stimulus.

The emission is intermittent and discrete. Like a pulse. It does not have a frequency, until it is absorbed(with reaction).......until then....it has a duty cycle.

If you feed the dipole with a function generator.....and feed one element with a precision rectified positive 180, and the other element with a negative 180.....continuously.......you will see no difference at the receiver. This should verify my premise. And this will prove that Maxwell was wrong.

And if you now apply my premise to moving objects..........you will see that there is no need for space-time to explain the constant V of EM. In other words.......the mystery of the V of EM is because the emission is instant. And discrete. NOT CONTINUOUS.

The experiment with the generator should show two things. It explains satellite radio links without space-time. Think hard and long about this dynamic. And it shows that a communication channel data rate can be doubled, because of that un-used time between pulses, without increasing bandwidth.

This experiment will make someone rich and famous. My disability has ended my experimentation.

My satisfaction comes from showing that no matter what you study, our universe is mechanical, not mathematical. And I believe that this experiment will prove it.

One should be able to see the snap and collapse of the voltage on the element with a differential probe, at the end of the 180 input. Leaving the element dead and neutral for the next 180 input. I hate to use the word collapse, because it implies the E and the M fall back into the circuit like an ignition coil. But with the element, the E and M fields fly out, and not in. A wave in the out direction. Instead of a field falling back into the circuit.

A field, and a wave, are different animals. An EM field has a angular structure and displacement, the EM wave has a linear structure and displacement. Emission is changing this structure from angular to linear, ........all this requires is a change in direction. Think of two tethered steel balls attached to a spinning hub. When we cut the tethers, the direction changes in an instant. This is why the V of c is constant. EM does not need time to be accelerated.

When absorbed, the wave stimulates free charge for 1/2 period duration. This lines up the charge of the absorber. Then.........the lined up charge of the absorber, takes another 1/2 period to react, by relaxing. It relaxes in the opposite direction. Giving a full period of detection. AND leaving the absorber dead and neutral for the next 1/2 period of stimulus.
