In nature not separate transverse and longitudinal waves.
Longitudinal waves require a medium. For many years,
empty space was considered to be empty. We now know
that "empty" space is not empty and has a structure
that teems with quantum particles, i.e. the "aether"
actually exists although not in the conventional
matter form that was earlier assumed.
I wanted to know if radio people observe the frequency doubling when
receiving signals from a dipole.
Frequency doubling can occur in non-linear systems.
Every powered transistor stage has a certain degree
of non-linearity. A passive antenna system is usually
linear.
