Default Fresnel effect.


A few years ago, broadband internet was hard to
get, and I played with the idea for a while to
have a wireless link.

Researching the possibilities and vendors I read
about "the Fresnel effect", that a beam between
two antenna's spreads out, and that it is not
enough to have a narrow sight contact between the
antenna's, one also needs some width, or else the
transmission is impaired.

Now, this is weird. This means that some 'photons'
follow a curved trajectory, that they are
influenced by the receiving antenna, at long
distance. Ok, quantum mechanics explains this.

But now, consider MMX. Think Fizeau. Is light
interference not a typical quantum fenomenon ?

Is that not the worst way of measuring an
relativistic effect ?

Calculate the numeric aperture of an antenna for your purpose vs. its
Airy circle. It is better to know something factual about which you
spew before you condemn all of physics for being as ignorant as you
are.

The Fizeau experiment was performed in 1849, jackass. You are
pathetic.
