how energy carried by electrons is converted into energy in form of photons by antenna?

They are tuned for a specific frequency so the structure plays the role here not not the material make up. And yeah the concept of transformer is used only but not for the task the transformer we usually employ that's what i was trying to say. You are not exactly explaining how waves are...

You can't see them they are not in the visible range.they are having frequency in terms of MHz to GHz.

I don't want to perform transformer action.my question here is completely different.Just go through it once more may be things will be little bit more clear to you. You are talking about antenna and radiation things at classical level i want the explanations at the atomic level.In antenna...

microwave.have heard somewhere all the emwaves have the same properties as light.parabolic antenna is an example of that,as reflection of radio-microwaves is observed here just like light.

hey nobody is here who can explain me these things?

i am not getting this. Its not laser light it is the output from a parabolic antenna.with the beam angle of about 10-15degree.

See the fig(attachment).I want to achieve this(shown in fig).

i need a lens that will make the rays parallel to each other & focal point at infinite.without much loss in the intensity.collimator lens kind of action but not at the cost of intensity.

If electric energy is supplied in the form of high voltage & low current & if the same energy is supplied in the form low voltage & high current will there be in difference in the photons emitted by the antenna?the frequency is same for both the cases.One electron can interact with just one atom...

If Anybody can answer my Question please do it.

50 60Hz waves can't be transmitted via antenna because the height of the antenna would be impractical.And as you said that at higher frequency photon are having higher energy so the same amount of photons can carry more energy if frequency is high.High amplitude causes higher losses so i would...

Amateur radio equipment are capable of producing and transmitting such high frequency.waves carrying power?So you agree that high power can be converted into high frequencies.Why this all power is burned in the input stage of transmitter tell me the reason of this phenomena.Is there any way to...

Thanks i am making this thing not for regular power transmission but for battery charging purpose of mobiles laptops etc.I have some ideas to improve its efficiency so that it can be employed for this purpose with some what more efficiency.I m just trying to initiate a new thing may be the next...

And in frequency modulation when the amplitude of modulating signal goes high the frequency of modulated signal is very high or getting higher during that period of time.whts this?it doesn't mean that high amplitude based energy is converted into high frequency based energy?i know in that case...
