Spherical radio
WebA result known as Birkhoff's theorem forbids spherical electromagnetic radiation. The statement of the theorem is that any spherically symmetric vacuum solution to Maxwell's equations must be static. It is rather simple to prove. In a spherically symmetric solution E and B must be radial. Make an Ansatz, E = E 0 exp ( i ( k ⋅ r − ω t)) r ...
