Hello!

I am a mechanical engineer and was surfing the web for some te10 information. I am strictly not familiar with electrical concepts beyond ohms law, but I am really curious to get this question answered.

Can the direction and range (depth?) of the microwaves emanating from a TE10 waveguide be controlled? for example if the waveguide terminates at point 0 (pointing to the right) on a number line, can I vary the distance the waves travels between point 3 or 2 or 5. If yes - how?

-5 -4 -3 -2 -1 0 1 2 3 4 5 6


I would appreciate your inputs!!!

Regards,
T.M.

An open waveguide is roughly equivalent to an antenna with about +10dBi gain / directivity. Sidelobes would be messier than a nice antenna. After that, you've got nearfield, far field and inverse square law. The amplitude fades away. Direction is where you point it.

It sounds like you need an antenna system.

Yes, I just bookmarked a few pages which explained antenna and "horn" terminology for microwave control. Could you post some links for antenna design / horn design which explain their effects and variations?

Thanks!!

TE 10 just means strong in the middle weak on the edges.
If your question is actually can you focus the energy like you would focus a light wave and the answer is yes but you'll need a lens made of dielectric.
The wave in general keeps propagating but a Lens could focus it to a hottish point.
10 dBi is 60 degree beamwidths, one lambda square. A bit high for waveguide by 3 dB I think.
